The ACR1252U USB NFC Reader III is an NFC Forum-certified PC-linked reader, developed based on 13.56Mhz contactless technology. It has a SAM (Secure Access Module) slot which can be used together with a SAM card for key diversification and mutual authentication, providing high-level security in contactless transactions. Post-deployment firmware upgrade is also supported, eliminating the need for additional hardware modification.

Compliant with both CCID and PC/SC, this plug-and-play USB NFC device allows interoperability with different devices and applications. It is thus ideal for unconventional marketing and advertising applications like smart posters.
