EMV Schemes

There are various EMV schemes out there. The term, EMV scheme, is normally used to refer to a concrete implementation of the EMV specification by a vendor. Another common term for the same is "chip card program."

The most famous EMV schemes or chip programs are VSDC (Visa Smart Debit and Credit) by Visa and M/Chip by Mastercard. Other EMV schemes with good market penetration are AEIPS by American Express or AMEX, JCB (Japan Card Bureau), etc.

While at the terminal, a chip card can be identified by reading the "Application Identifier" (AID) on the chip, an online transaction message based on ISO-8583 doesn't contain the AID.
