Hi.I use this module with Google Pay. It dont work. RATS always return collision error or timeout. It is mistake on pcb. Y1 is 27.0 mhz. It must be 27.12. I replace Y1 to 27.12. It work fine now as Pay Terminal with smartphone.
Best regards, Volkov Serge

ok. Resonator must be 27.120MHZ not 27.000. If resonator is 27.000 RATS work fine with PayPass card, but not work with SmartPhone as PayPass card. RATS return error.
