Payments and payment systems - chip card protocols.
An EMV card is a chip card that complies with the EMV protocol.
The protocol is designed to enable secure contact and contactless transactions and other emerging payment technologies.
Under the protocol, EMV® Chip Specifications describe the requirements for global interoperability between chip-based payment applications and acceptance terminals.
The EMV® payment device must communicate with a chip reader in the acceptance terminal - either contact or contactless - to enable the transaction.
This protocol is defined and tested by EMVCo.
