We have a client who uses WorldPay for CC transactions using a certain pos system. We are trying to implement a system by which we can identify the customer based on the card type & number. Can we do this? If so - we are thinking of a client level application that can keep track of these events?
1) This is a US based client
2) I am not sure when you talk about integration - if I understand it correctly - it is through PoS that they are integrated into WorldPay.
Seshu,
It is possible, depending on the type of card reader integrated into the system.
If you are using an MSR, you can just read the customer name and card number from Track 1. You can then parse out the 1st character of the card number to get the card type and the last four characters to help identify the card for future transactions. You can also parse out the name. Note that the code to do this may cause your payment application and POS to go out of PCI compliance, especially if you are storing the parsed data on the POS or other storage location.
If you are using EMV (depending upon the EMV device being used) you can query the EMV ProcessTransaction returned string for the CmdResponse, which contains the CardholderName, CardType, and AcctNo (masked) elements.
Great questionsmkonnekt - what type of integration does your client have with Worldpay? is it US domestic or a global integration such as Access? Narrowing down can help me get you to the right audience.
