When it comes to payment options, nothing is more convenient than electronic payment. You don’t have to write a check, swipe a credit card or handle any paper money; all you have to do is enter some information into your Web browser and click your mouse. It’s no wonder that more and more people are turning to electronic payment — or e-payment — as an alternative to sending checks through the mail.
The credit card payment information is being validated using the secure gateways that are provided by the different banks like citi bank…etc.The only thing that u need to do is to provide the link to the secure gateway payment that is provided by different banks in your application.Once the user had entered the credit card information then a check is made against the information that is available in the data base.Generally the information related to the cards is being maintained in the legacy systems which are nothing but the main frame systems.The information from these systems is refreshed in to the other RDBMS on a daily bases by running the batch process.This is done to do all the validity checks when the payment is made.The information that is being exchanged is done in the https for the security reasons and also the encryption is used to secure the information that is being exchanged.
