1. Introduction
E-Banking is not something new to Pakistan. The first ever ATM machine was installed in 1987 in Pakistan. Till late 1990s, the installation and growth rate of ATM machine were remained low and slow. However, the real growth in ATM machine and ATM cards issuance were seen in 1999 after establishment of national switches links and accelerated the issuance of ATM cards with the SBP (State Bank Pakistan) circular 2002. The issuances of cards for accountholders were mandatory to every bank and must connect to two ATM links [1] . SBP played a vital role in the e-banking evolution by providing supporting atmosphere. With determinations of State Bank Pakistan as a supervisor, it covered way for banks to issue cards to accountholders and provide entrance to bank financial records over ATM machine by integrating the bank with single link or multiple links. State Bank of Pakistan later directed in 2006 the two networks must have interconnectivity, which made it conceivable for any account holder of any bank to take the cash out from any bank across the country via ATM card [2] . The SBP has introducing new rules to further improvement of the quality of services rendering by the various banks in Pakistan and make it ensure the account holder services have not be compromised. With the economic growth in Pakistan the financial activities increased [3] which led to benefits for ATM networks. The vast number of financial activities by the ATM network also led to provide innovative solutions to accountholder such as easy, fast, cost effective and secure ATM links. The various banks in Pakistan offer different services to their cardholders for example, fund transfer to same and different banks, payment of utility bills by cards and inter banking transaction facilities [4] . This growth in e-banking will led to introducing the branchless banking concept in banking sector. The banking sector also introduced various cards for their customers such as Debit card, Credit cards, and Visa cards. Figure 1 shows the total installed ATM machine, online branches, plastic cards, e-banking transactions and other kinds of transactions in Pakistan [5] . Due to the integration of internet services with banking sector many challenges have been raised [6] . This research paper indicates some of them by conducting the survey. The article consists with five sections. Section one comprises the introduction of e-banking. Section two covers the e-technologies and Section three presents the e-transactions. Section four indicated the challenges in e-banking and finally Section five drew the conclusion.

tor compact the charge of operation and amplified the swiftness of deals extensively. The nature of financial mediators made banks advance their invention tools by concentrating on dissemination of products. In other words, the advancement of banking information technology has been essentially motivated by variations in scattering networks such as from tele-banking, phone-banking, pc banking over-the counter (OTC) and automated-teller-machine (ATM), and most recently internet banking (IB) [7] . The various commercial banking sectors go through with rapid transformation due to information and communication services, as the international and national economy grow and spread towards market and industrial completeness. A main vigor behind these progresses is an information technology, which breach the industrial, geographical and regulatory barriers and increases the production of innovative services, products, systems oriented business, developing more information, market opportunities and management processes [8] .
