EMVCo reference design for the ST25R3911B high performance HF reader

The ST25R3911B-EMVCO reference design is a ready to use contactless payment terminal implementing a complete EMVCo Level 1 software stack. It allows contactless testing to be made with appropriate test systems, according to the EMVCo specifications.

The ST25R3911B-EMVCO reference design is equipped with a 2.4 inch resistive touch panel, surrounded by a two turn RF antenna, it shows a typical use case in contactless payment.

The STM32L476 100-pin LQFP MCU serves as host controller for the ST25R3911B and connected peripherals.
