Authorization with Contactless EMV and Online PIN {#cp-emv-contactless-onlinepin-auth-intro}
============================================================================================

For an EMV contactless payment, the customer taps the card on the terminal. The terminal and chip use near-field communication (NFC) to communicate with each other. For an online PIN transaction, the customer uses a PIN to verify their identity and the issuer verifies the PIN.  
Online PIN transactions are supported by these card types:

* Visa
* Mastercard
* American Express
* Discover
