The ACM1281S-C7 contains a SAM slot for customers wanting to integrate a SERIAL contactless module into their embedded system using its RS232 serial interface. This 13.56Mhz module supports ISO14443A/B for popular cards like Mifare technology. The ISO7816 compliant built-in SAM (supporting T=0/T=1) faciltates that extra layer of security for contactless transactions. The ACM1281S-C7 firmware is field upgradeable and supports extended APDU (maximum 64 bytes). The module is particular suited for vending machine payment, gaming and other systems demanding a high level of security wanting to use existing serial ports.
