Need a NFC/RFID reference design

Other Parts Discussed in Thread: TRF7970A

Hi team,

The customer has an application question for NFC/RFID as below:

He would like to design a swiping card system through  NFC or RFID. E.g There are 10 people and everyone has a card. 

There are 10 lights, their numbers are from 1 to 10.

The first people  swipes the card, then the 1 number light is turned on and other lights are turn off. 

Then other people can and so on. 

For the customer's application, would you recommend a suitable NFC or RFID device and a similar reference design?

Best Wishes,

    Hello Mickey,

    I am a bit confused. Swiping to me would mean mag strips are involved, which aren't NFC/RFID. Is that just a terminology used, or is it actually an application like that?

    In any event, the best device to interface with NFC/RFID cards is the TRF7970A.

    See this app note for details: www.ti.com/lit/pdf/sloa227
