The ACR1251U USB NFC Reader II offers advanced features such as firmware upgradeability, a SAM (Secure Access Module) slot, and support for NFC tags and devices. It is ideal for contactless applications with added security functions. Through the SAM, key diversification and mutual authentication are made possible, restricting the exposure of keys and limiting the possibility of keys being stolen. This provides a high level of security in contactless operations.
ACR1251U is suitable for any contactless smart card application such as personal identity verification, network login, online banking, and micropayment. With its enhanced NFC features, ACR1251U is also ideal for non-conventional NFC applications. Such applications include smart posters for advertising, marketing, and communication purposes.
Furthermore, ACR1251U is PC/SC-compliant, allowing interoperability across different applications and platforms. ACR1251U also supports remote post-deployment firmware update, which eliminates the need for additional hardware modification. With its compact size, trendy design and rich features, ACR1251U enables you to fully enjoy the convenience of using NFC applications.
The ACR1251U comes with an optional stand to hold the smart card reader at an optimal angle, so that users can tap contactless cards or NFC-enabled devices onto the ACR1251U with ease.
