TRF7963A: NFC Read mode application

Part Number: TRF7963A
Other Parts Discussed in Thread: TRF7964A, TRF7970A

Hi Team,

We want to use NFC reader & Passive TAG for our application (identifying the TAG by reading it). I have two technical questions, could you please help me to get it clarified.

 

1) which standard would be enough for our application for selecting NFC Reader IC and NFC TAG:

1)      ISO/IEC 14443-4 Type A;

2)      ISO/IEC 14443-4 Type B;

3)      ISO/IEC 15693;

4)      ISO/IEC 18092;

5)      ISO/IEC 21481;

6)      MIFARE® Classic;

7)      ISO/IEC 18000-3M1”

 

2) I would like to know TAG IC will support any encryption/cryptographic modes to secure the data?? Or to select a TAG which standard (like type-4) support that feature for security purpose.

Thanks & Regards,

Bhargavi

    Hello Bhargavi,

    For question 1:

    The first 3 protocols you listed would be best:

    1)      ISO/IEC 14443-4 Type A;

    2)      ISO/IEC 14443-4 Type B;

    3)      ISO/IEC 15693;

    For question 2:

    The following options are available from TI on a reader perspective. We do not make any tags with built in Encryption also you can use encryptions like SHA on data stored in tags.

    MIFARE Classic:

    • The recommended authentication example requires either the TRF7970A or TRF7964A and is described in Using Special Direct Mode With the TRF7970A

    • Alternatively, the TRF79xxA devices covered in this guide can support MIFARE™ Classic tags by using Direct Mode 0 which requires the host MCU to run at a multiple of 13.56MHz in order to encode/decode the raw subcarrier signal. The firmware example for this can be requested here: http://www.ti.com/tool/TRF796X_TRF7970X_MIFARE_12_2013

    MIFARE DESFire AES authentication example is provided in MIFARE DESFire EV1 AES Authentication With TRF7970A. This example does not include example firmware for the exchange of encrypted data, only initial authentication with an AES key.
