This depends on your definition of RFID. It's most definitely possible to use our chips for RFID solutions, all our current chips are in the 2.4 GHz frequency band, which I believe isn't part of a lot of the regular RFID standards.
If you don't have any particular frequency requirements, I'd say that all our chips are possible options, both the nRF24L01+ transceiver, the older and smaller nRF24LE1 SoC and the newest nRF51822 SoC. The latter might be overkill for such solution, even though it would most certainly be possible to make.
Thank you. I will check those. Explain: People are looking for a self-powered (harvesting) transponder for tagging things. So that the tag read range can be several meters. Existing passive tags require too much illumination power to meet that distance requirement. (The RF illumination power exceeds safety or compatibility limits). Otherwise, long-range (active) tags require a battery and that is not optimum, when long-term storage is a consideration. Freqs of 2.4 and above would allow smaller antennas. I dont know why rfid designers dont use the higher GHz freqs...works well for radar, huh? Some thought could surely be given to the problem of interference with existing services, such as using a very low pulsing duty cycle, etc., with the rfid system. - - John
