The ACM1281S-C7 Serial Contactless Reader Module with SAM Slot was designed based on 13.56 MHz technology for fast and easy integration into embedded systems. It is a plug-and-play device that does not require any driver installation.

ACM1281S-C7 supports ISO 14443 Parts 1-4 Type A and B cards, and MIFARE® Classic series. It has a card reading distance of up to 50 mm (depending on tag type). Moreover, it has an ISO 7816-compliant built-in SAM (Secure Access Module) slot, which can be used with a SAM card for high-level security in contactless transactions. 

This reader module with integrated (on-board) antenna comes with an optional serial cable. It has additional features like USB firmware upgradability and extended APDU support. Lastly, ACM1281S-C7 makes use of high-speed communication for contactless cards (maximum of 848 kbps), which makes it suitable for highly demanding applications. Its RS232 serial interface can accommodate more devices, such as vending machine payment systems, kiosks, gaming machines, and other integrated systems, which have different serial ports.
