How Do I Prepare My Contact/Contactless EMV Reader for EMV Transactions?
Answer:
For Contactless EMV, we need at least 3 components for a successful transaction:
AIDS - application identifiers, which allow the card to communicate with the reader (card has application A, reader has application A, they can talk)
CAPKs - certificate authority public keys, which allow the card to perform offline data authentication (ODA) to determine the validity of the certificate on the reader
Group Configurations - there are several contactless groups on the reader that can be configured, depending on who you plan to process with / through.
You can load sample AIDs, CAPKs, and groups using any of our SDK demo programs. Once that is done, you should be able to perform a sample contactless transaction with a supported card.
For Contact EMV, it is similar.
AIDS - Applications exist on the card and in the reader. These applications are brand-specific (Visa, Master Card, etc). During the Application Selection part of an EMV transaction the reader and card exchange information about what applications they support and an application is selected for the transaction. The card has application A, the reader has application A, and they can talk).
CAPKs - certificate authority public keys, which allow the card to perform offline data authentication (ODA) to determine the validity of the certificate on the reader
