NFC devices. It has an ISO 7816 Compliant Class A SAM (Secure Access Module) slot which can be used together with a SAM card for key diversification and mutual authentication, providing high level of security in contactless transactions. Postdeployment 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. These NFC features make the ACR1252U ideal for NFC applications like Smart Posters for advertising and marketing purposes with most NFC-enabled mobile phones and

SIM cards in the market.
