Java program for credit card, ATM payments

I wrote a Java POS program, and the my client wants to add a feature where a person can use a credit card or ATM card for payment. What I understood was that she wants the POS to handle the payment processing. But I noticed in dept stores that they had separate machine where t开发者_Python百科he cards are swiped for the payment, and they get a copy of the receipt. I wonder if you can integrate that feature in the program. If it is possible, are there any specific libraries I can use for that feature? Thanks!

You would need to contact your client's credit card processor and see if they have an internet gateway and library/API available. Many do.

@Jairo, The services you want to avail is called Merchant Acquiring Service. For online payment or for using the POS systems, one need to contact Acquiring Service Provider (such as TSYS, FDMS etc.) where your client need to register the POS and start the transaction. For More information, just google "Merchant Acquiring".

Hope this will help.
