EMV Contactless Payment Flow Visualizer
Step-by-step visualization of an EMV contactless payment transaction. Walk through every APDU command and response — from card detection to cryptogram generation. See exactly what SELECT PPSE, GPO, READ RECORD, and GENERATE AC look like on the wire. Essential for EMVCo kernel developers and payment terminal testers.
This is a reference trace of a typical EMV contactless transaction (Visa payWave / Mastercard PayPass / Amex ExpressPay). Actual APDU data varies by card and terminal configuration. Use our EMV Cryptogram Visualizer to compute ARQC/ARPC with your own data.
