Description

The NXP® MIFARE SAM AV3 is the third-generation MIFARE Secure Access Module (SAM), designed for flexible performance in today’s IoT, secures keys and protects assets. The MIFARE SAM AV3 extends functionality to include support for NXP’s DNA range of the NTAG, ICODE, and UCODE families beyond MIFARE ICs. It is an ideal add-on for edge computing nodes and end nodes such as reader and POS terminals, toll gates, and door locks. Optimized for use with the product types in these families that offer Transaction Message Authentication Codes (TMACs), the MIFARE SAM AV3 secures keys and protects assets in the latest IoT applications.

The MIFARE SAM AV3 raises the bar on flexibility by supporting programmable logic, too, so you can integrate a proprietary algorithm for key diversification or implement a full business flow that executes with just one call. Developers can also write their own code while re-using the intrinsic cryptography functions of the MIFARE SAM AV3. To simplify the development of customized logic – a process that requires eligibility, tool investment, and specialized skills – NXP partners with design houses that offer code development and other services tailored to the MIFARE SAM AV3.

The MIFARE SAM AV3 offers an easy way to add security to all of today’s more important IoT applications, and helps to create faster, leaner designs of edge computing nodes.

The efficient X-mode configuration allows direct communication with RF-frontend ICs without using the SAM as a cryptographic coprocessor to achieve higher application performance.

For a growing number of smart card applications, where service providers need to ensure highest data and transaction security, NXP´s MIFARE SAMs (Secure Access Modules) are the perfect solution. It turns even the simplest reader into a high security transaction device. With its on board cryptographic co-processors with 3DES, AES and PKI capabilities, our hardware solutions offers superior cryptographic features for a variety of secure infrastructures, including access management and automatic fare collection. And a new version of NXP’s secure access module, the Mifare SAM AV3, supports contactless transactions and NXP’s NTAG DNA and Icode DNA as well as longer-range Ucode DNA products.

Unlike other SAM card products on the market today, MIFARE SAM AV2 has proven interoperability with all of NXP’s broad card portfolio, (MIFARE Ultralight, MIFARE Ultralight C, MIFARE 1K, MIFARE 4K, MIFARE Plus, MIFARE DESFire, MIFARE DESFire EV1 and SmartMX solutions), making it the most versatile and secure SAM solution on the market today.

Available in Mini SIM (2FF) and Micro SIM (3FF).
