Peculiarities of Host EMV Integrations

A lot of companies have faced the challenge of EMV integration. The best way out is to start from a research to gain a deep understanding of the problem.  So have a look at the changes, which need to be introduced into payment gateway logic for the gateway to be able to support EMV.

Firstly, it is important to understand that there are specific fields for EMV data processing that a gateway needs to support. In general, there are two sets of them: the tag data read from the chip and the information about general terminal capabilities.

Secondly, some changes should be done in the response field. The issuer can return a configuration script that needs to be passed back to the card for a subsequent update, so the gateway needs to accommodate this value.

Thirdly, specific fields should be printed on the receipt. The list of the mandatory fields on the receipt and more information on the above-mentioned features can be found on #Paylosophy
