Please excuse me if my question is naive.
We are doing some tests with the TRF7970A EVM and found that it could not find an H.I.D. iClass 2K/2 card, which is ISO 15693 compliant. My understanding is that if the iClass card uses ISO 15693 standard for communication, the TRF7970A EVM should at least detect the card. Is it because the iClass has H.I.D. proprietary protocol implemented which prevents the EVM from detecting it?
Any help is appreciated!
HID card is not ISO15693 compliant to -3, only -2. This means actually quite alot, since they don't respond to the same commands and the CRC is also different. But you can see the attached docuement which I did and was verified by the Inside Contactless guys (this is the silicon being used in the HID cards) as correct to give you some hints here about what you would need to do for your own firmware development efforts.
