1. INTRODUCTION 1.1 PURPOSE The main purpose that banks have been serving since their inception is keeping our money safe for us. While keeping our money safe, they also let us earn a certain amount of interest on the money deposited with them. Traditional banks have been doing this, and internet banks continue the same function. The only difference is in the way the transaction is made. We all know about internet banking and most of us use it quite often as well, Internet banking basically allows you to be able to do everything that you can in your regular banking institution, only with the benefit that you can do it all right from the convenience of your own home. Not only is this great because you can be comfortable and have peace of mind knowing that you can keep track yourself of all your banking issues, but as well it allows for more ease because you never have to worry about rushing out and making it to the bank
