ACR1252U - USB NFC Reader III (NFC Forum Certified Reader)

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.

ACR1252U is capable of the three modes of NFC, namely: card reader/writer, card emulation and peer-to-peer communication. It supports ISO 14443 Type A and B cards, MIFARE®, FeliCa, and ISO 18092compliant NFC tags. It also supports other NFC devices with an access speed of up to 424 Kbps and proximity operating distance of up to 50mm (depending on tag type used).

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.
