ABSTRACT:
The new age information technology is
bringing about sweeping changes in the banking industry. The entire system
became more convenient and swift. Time is given more importance than money. IT
enabled banking offers multiple advantages over traditional banking channels.
The present study was conducted in public sector, private sector and foreign
banks of Delhi. Multistage random sampling was used for selection of sample.
Three banks (State Bank of India, Punjab National Bank and Canara Bank) among
public sector banks, two banks (ICICI and HDFC) among private sector banks and
one bank (Standard Chartered) among foreign banks were selected for the study.
The present research focuses extent of use of IT enabled services by customers
and their problems. It was found that very few customers were using IT enabled
services, still these services are not so popular among the customers. ATM was
found the most popular IT enabled banking services in all the three types of
banks. Further, it was found that personal variables of respondents had an
impact use of IT enabled services such as credit card, ATM and Internet
Banking.
KEYWORDS: Public sector banks, private sector banks,
foreign banks, ATM, internet banking.
In India the banking scenario
has undergone tremendous changes and they are facing tough competition by their
foreign counterparts. Various changes in regulatory mechanism and competitive
reasons have led to utmost requirement of total computerization of the Indian
Banking Industry. The Banks cannot think of innovative products and services
without IT support. The total automation of banking transactions ensures 24x7
Days service to the customers without interruption and break.
The new age information
technology is bringing about sweeping changes in the banking industry, forcing
them to re-engineer many of their basic processes and systems. The Banking
Industry is service oriented, but at the same time it needs profit to enhance
the value of all stakeholders. Previously the Banking services were merely
accepting deposits and lending advances to the needy along with some ancillary
services.

Currently, overall banking in
India is considered as fairly mature in terms of supply, product range and
reaches even though, reach in rural India still remains a challenge for the
private sector and foreign banks. With the advancement in technology, services
provided by banks have become more easy and convenient. The competitive
character has been further promoted by facilitating the entry of new players,
especially foreign banks. The country is flooded with foreign banks and their
ATM stations. Efforts are being put to give a satisfactory service to
customers. Phone banking and net banking are recent innovations. The entire
system became more convenient and swift. Time is given more importance than
money. IT enabled banking offers multiple advantages over traditional banking
channels. Some studies done earlier points out that cost of service per
customer reduce drastically when bank uses technology.
The foremost thing required for
the growth of the IT enabled banking is more usage of IT enabled channels
compared to the branch banking by customers. The future of banking will be one
in which customers can address most of their needs through self-directed means
and will be how effective a bank is in getting its customers online.
The present study was conducted in public
sector, private sector and foreign banks of Delhi. Multistage random sampling
was used for selection of sample. Three banks (State Bank of India, Punjab
National Bank and Canara Bank) among public sector banks, two banks (ICICI and
HDFC) among private sector banks and one bank (Standard Chartered) among
foreign banks were selected for the study. Two branches each of the above banks
were randomly selected for conducting the study. After identification of
branches, the researcher visited banks under study and selected 50 customers
randomly from each branch of the bank (total 12 branches and 6 banks) making a
total of 600 customers as sample.
The data was collected
regarding the extent of use of IT enabled banking services, number of years for
which customers have been using these services and finally the reasons for not
using them. A total of nine services used by the customers were analyzed. These
included –
1. Electronic Clearing Services
2. Electronic Fund Transfer
3. Utility Payment Services
4. Credit Card
5. Automated Teller Machine
6. Internet Banking
7. Centralized Banking
8. Foreign Exchange System
9. Real Time Gross Settlement
System
The data was analyzed and the
findings are presented separately for 3 categories of banks-
IT enabled services in public sector banks
The data was scrutinized for
the total sample 300 customers of public sector banks and further the extent of
using these services was analyzed.
Fig. 1
: IT enabled services used by customers
of public sector banks
·
Analysis
of data revealed that only one – fourth of the customers in public sector banks
were using ECS, among them majority of the customers were using this
service up to great extent.
·
Likewise,
Electronic Fund Transfer was also used by only few customers (17 %) in
the public sector banks, though majority of them were using up to great extent
(15.7 %). Electronic Funds Transfer (EFT) is a system of transferring money
from one bank account directly to another. One of the most widely-used EFT
programs is Direct Deposit, in which payroll is deposited straight into an
employee's bank account, although EFT refers to any transfer of funds initiated
through an electronic terminal, including credit card, ATM, Fedwire and
point-of-sale (POS) transactions. It is used for both credit transfers, such as
payroll payments, and for debit transfers, such as mortgage payments.
·
ATM
is
the most popular electronic banking services among all e-banking services.
Majority of the customers were using ATM up to great extent (77.7 %). Only few
customers were not using ATM and maximum customers reported that they did not
need ATM. This may be due to the fact that generally old people did not use ATM
as they followed traditional method of transactions in their respective banks
and found it more convenient. This showed that use of ATM was found very
popular in public sector banks. The results agreed with Rogers et al (1996),
who reported that the majority of ATM usage was by middle age compared to the
aged.
·
Credit
Card is a plastic card used to make a purchase on credit. The issuer of the
card will later collect payment for the purchase. If payment is made after the
grace period, interest will be charged on the account. Surprisingly, the credit
card facility was not found very popular among the customers of public
sector banks. Only twenty per cent customers were using credit cards, among
them, majority were using up to great extent.
·
Utility
Payment service is
the easiest way to manage and pay utility bills through bank’s counter, e
banking and ATM anytime, anywhere without standing in queues. When the data was
analyzed regarding utility payment services, it was found that a small
percentage of customers, i.e., only 5 per cent in public sector banks
were using this service up to great extent.
·
The
fig. 1. showed that majority of the customers were not using internet
banking and reasons reported by them were no need (48.1 %), security
concerns (25.8 %), complicated procedure (16.1 %) and unawareness (9.9 %).
Online banking provides an easier and more comfortable way to carry out
transactions. However, it continues to present challenges to the financial
security and personal privacy. Hence, people reported having some security
related reservations while using internet banking. Kaynak and Harcar (2005)
also observed that security problems were the most important reason given for
not using online banking. Their results showed that security problems, like
hackers and fraud, were determining aspects in Internet service presentation.
In this concept, trust and security were factors supporting a positive view of
Internet banking service quality.
·
Centralized
banking was
the second most popular IT enabled banking services among the customers of
public sector banks. Almost 39 per cent customers were using centralized
banking. Majority of them were using this service since 5-8 years and up to
great extent.
·
Foreign
exchange system was
used by a negligible proportion (1.66 %) of total customers.
·
RTGS
was used by only 8 per cent of the total customers in public sector banks.
Mostly RTGS is used by businessmen as they have to transfer money in bulk. This
service is not so useful for service class people.
IT enabled services in private banks
The above mentioned services
were studied in private banks also. The findings presented are as follows-
·
The
most popular IT enabled banking services in private banks was found to be ATM
(89.5 %), followed by centralized banking (52 %) and internet
banking (36 %) up to great extent.
·
The
customers who were not using these services reported various reasons such as
the service not required, complicated to use, unawareness and security
concerns. Madu (2002) also stated that strong concern about the security was
found one common issue related to unwillingness to use internet banking
services. Cunninghum (2003) reported that security was one of the most
important future challenges, because customers fear higher risk in using the
web for financial transactions in internet banking.
·
Electronic
Clearing Services was
used by little less than half of the customers in private banks. They were
using this service since 1-4 years. The customers who were not using this
service commented that they did not need ECS, some of them were not even aware
of this service.
·
Likewise,
Electronic Fund Transfer was used by 42.5 per cent of customers. Almost
half of them were using this service up to great extent and majority of them
were using this service since 1-4 years.
·
Utility
Payment Services were
used by 37 per cent customers.
·
Credit
Card (30 %), Foreign Exchange System (1.5 %) and RTGS (15 %) were
adopted by very few customers.
Fig. 2
: IT enabled services used by customers
of private banks
The results showed that a trend towards
adopting IT enabled services is increasing in private banks. Though customers
had some doubts related to security and privacy. Customers were not aware of
some of these services. Hence, these findings are pointer to the fact that
their banks are needed to create awareness among their customers regarding new
IT enabled services. Banks should clear suspicions regarding their security and
privacy when using IT enabled services (Table 9 Appendix VII).
Joseph et al (2003) stated that the
installation of customer friendly technology (such as menu driven automated
teller machines, telephone and Internet banking services) as a means of
delivering traditional banking services has become common place in recent
years. Traditional brick and mortar banks are using technology to meet the
competitive challenge posed by online banks, as well as a method of reducing
the cost of providing services that were once delivered exclusively by bank
personnel.
IT enabled services in foreign banks
Fig. 3
: IT enabled services used by customers of foreign banks
An attempt was made to
scrutinize the data on the use of IT enabled services by the customers of
foreign banks along with comparing it with use of these services by the
customers of public and private banks. This was done to make an inter-bank
comparison. The data after scrutinizing showed the following results with
regard to IT enabled services in foreign banks.
·
Various IT enabled services were popular among the customers of
foreign banks such as ATM (100%),
centralized banking (73 %), credit card (71 %) and internet banking (67 %).
More than half of the customers were using Utility
Payment Service and nearly half of them were found using Electronic Fund Transfer. The IT
enabled services which were less popular among foreign banks were Electronic
Clearing Services (11 %), Foreign exchange system (9 %) and RTGS (11 %).
Inter-bank comparison
·
The findings revealed that more number of customers in the private
banks were using Electronic Clearing
Services as compared to public sector banks and foreign banks.
·
The use of Electronic Fund
Transfer was more in private banks and foreign banks in comparison to the
public sector banks.
·
Utility Payment Service was used by maximum customers of foreign banks followed by private
banks, whereas, only very few customers (5 %) were found using this service in
the public sector banks. The reason behind this may be attributed to the fact
that the customers of foreign and private banks could be more computers savvy
rather than the customers of public sector banks.
·
The Credit Card facility was used by majority of the
customers of foreign banks and private banks, as against very few customers
were using this facility in the public sector banks. It seems that most of the
customers were concerned about security features of credit card. Majority of
the customers in all the banks reported security features as their main concern
while not using credit card facility.
The other reason may be mostly young customers were found using the
services of private and foreign banks and they were more attracted with IT
enabled services.
On the whole, a negligible
number of customers were found using Foreign Exchange System in all the banks.
Only few customers were using RTGS in all the three categories of banks. After
comparing all the three categories of banks, it was found that customers of
private banks were using RTGS more than foreign and public sector banks.
Further, these findings are
pointers to the fact that ATM seems to be the most popular IT enabled banking
service among customers these days in all types of banks. Further, the results
showed that internet banking was more popular among the customers of foreign
banks and private banks as compared to the customers of public sector banks. Other researches had also indicated a number of reasons for the customers’
motivation to use E-banking services such as freedom of time and space, speed,
convenience, 24 hours a day availability and price incentives (Mattila,
Karjaluoto and Pento, 2002). In a study
entitled “Role of information technology in banking industry” conducted by
Rahman I. U. (2007) in India, it was found that there was a positive relation
between implementation of IT and delivery of service.
CUSTOMERS’
OPINION ABOUT THE IT ENABLED SERVICES
The above discussion throws light on the fact that customers
were found using the IT enabled services in all the categories of banks, but in
varying numbers. Some services were found to be the most popular ones, whereas,
others were not so. This may be due to a number of problems faced by them in
availing these services. Investigator
attempted to find out what the customers’ think about these services. For this,
customer’s viewpoints had been taken on following areas-
ATM related problems

Though the results, already
discussed, had shown that ATM was the most popular service in all the three
categories of banks due to 24 hours service and fast withdrawal of cash without
personally visiting the banks, but still the customers reported a number of
problems faced regarding ATM. These were lack of cash, location of ATM and
improper functioning of the machine. Out of these, improper functioning of
machine was found to be the main problem, reported by almost 70 per cent
customers in public sector banks, by half of the customers in private banks,
whereas, in foreign banks, this was faced by only 35 per cent customers. These
findings are indicative of the fact that foreign banks are more particular to
provide customer friendly services. The results are in same line with Abdulwahab (2010), who reported that a
major problem allied with the usage of ATM was pervasiveness of network and
cash trapping. These were attributed to poor network and unavailability of
funds from customer’s accounts of residence. One of the security measures
employed for safeguarding of customer’s account was to withhold the ATM card
whenever the integrity of Personal Information Number is violated, normally
three attempts were allowed given an intruder a 0.06 per cent chances to get
the correct PIN before the card is withheld (Kuhn, 1997).
Quality criteria identified by the customers for
Internet Banking
Fig. 4
Quality criteria for internet banking
Four quality criteria for
internet banking were considered by the customers, i.e., speed,
security, reliability and easy to navigate. In public and private banks,
maximum customers considered security as an important criterion for internet
banking followed by its speed and reliability. Results showed a different
picture in foreign banks where the customers were more concerned with the speed
of internet banking followed by its reliability.

The customers were also
interrogated about features for reliability of internet banking. Important
features indicating the reliability of internet banking turned out to be “site was update and running all the time” and
“site pages did not freeze up” when all the information was entered.
Speed of login
Fig. 5 : Speed of login
Out of total sample
respondents, almost half of the customers reported that speed of the login was
fast. This was reported by the customers of all the banks. The reason may be
highly competitive environment and adoption of modern technology by all the
banks.
Speed of log out
Fig. 6
: Speed of log out
Speed of logout of account in
the internet banking was reported fast by 64.2
per cent customers of foreign banks, which was 47.3 per cent in the private banks and 30.4 per cent in the public sector banks. This
shows that foreign banks are more efficient in the internet banking than
private and public banks in this regard. These findings throw light on the fact
that in this competitive world, if the public sector banks and private banks
have to survive, they have to provide customer friendly services.
The confirmation of transactions from the bank’s
website
On the whole, 44 per cent
customers reported that their bank’ site confirmed after every transaction.
Inter-bank comparison showed variation with minimum customers in public sector
banks reported that their bank’s site always confirmed after every transaction
and maximum customers (52.2 %) reported the same in foreign banks. Further,
maximum customers in foreign banks stated that their bank’s site mostly
provided quick information of transaction while on the contrary, minimum, i.e.,
28.3 per cent customers reported the same in public banks.

misused by the bank while this percentage was little less in the public sector
banks and private banks, i.e., 30.4 per cent, each.

Majority of the customers i.e.,

website was easily accessible. In comparison within the three types of banks,
it can be seen that more customers in the public sector banks were of the view
point that internet banking website was easily accessible, simple and easy to
browse.
USE OF IT ENABLED SERVICES AS
AFFECTED BY AGE, GENDER AND OCCUPATION
In
order to find out the effect of personal variables on use of common IT enabled
banking services, which included credit card, ATM and internet banking in all
the three types of banks, data was analyzed. The personal variables of
respondents such as age, gender and occupation were correlated with use of IT
enabled services such as credit card, ATM and internet banking. The findings
are presented here in three heads-
Correlation

level of significance
Table 6 reveals that age of
respondents in public sector banks had significant negative correlation with
the use of credit card, ATM and Internet Banking by them. It can be concluded
that more young respondents were using credit card, ATM and Internet Banking.
The reason behind this may be attributed as young generation is more computer
savvy than their older counterparts.
Analysis of data revealed that
gender of respondents was significantly correlated with the occupation, use of
ATM and Internet Banking. It can be stated that that majority of male
respondents were using ATM and Internet Banking.
Correlation
between variables in private banks
Personal
variables of respondents in private banks may have an impact on the use of
various IT enabled services by them. Hence, correlation coefficient between
personal variables of respondents and their use of IT enabled services was calculated
in private banks.
Table 6 shows that age had
significant negative correlation with internet banking. It can be said that
more young respondents were more using internet banking facility. Further,
occupation was found negatively correlated with internet banking. It points out
that business class was using more internet banking than the service class.
Correlation
between variables in foreign banks
Correlation
between personal variables of respondents and use of IT enabled services by
them was also studied.
Age of the respondents was
showing a trend of negative correlation though non significant with use credit
card, ATM and Internet banking. It may be said that more young respondents were
using IT enabled services. Further, Table 4.25 shows that business and other
class respondents were using internet banking more.
CONCLUSION:
It
can be stated from the above discussions that public sector banks are also
making efforts to stay in the competition of modern tech savvy banks. They are
also providing various IT enabled services such as online transactions, ATMs,
Utility Payment Services and so on.
Private sector banks and foreign banks may have appeared to be winning
the race through their high technology and customer friendly approach, but
public sector banks, with their vast client base and unparalleled treasury of
trust, are evolving customer-friendliness and adopting high technology and fast
pace. Public sector banks have also understood that in the era of competition,
customer satisfaction is the key to success. Adoption of high technology and
customer friendliness will make public sector banks, a leading one in
India.
Further, in nutshell, it can be
concluded that personal variables of respondents like age, gender and
occupation have an impact on use of IT enabled services such as credit card,
ATM and Internet Banking. Younger respondents were found to be using more
internet banking in all the three categories of banks. As far as occupation is concerned, business
class were using more credit card, ATM and Internet Banking.
