RFID Tag over Bluetooth?

[Oleh]

Dear

Is there a possibility within Nordic SoC to make a passive RFID Tag which will connect to SmartPhone via Bluetooth?

Just like µBlue Series, but smaller and using energy harvesting? Is it feasible at all?

Thank you&Regards

It isn't clear to me exactly what you need, but any kind of BLE Peripheral device can be made with the nRF51822. However, the radio is a pure 2.4 GHz device, so it can not be used directly with any kind of passive RFID solutions, which usually employs completely different frequency bands.

You can make a device that can be read with a BLE capable smartphone, and if you have some kind of energy harvesting, it would probably be possible to make it battery-less. However, it will not be possible to make it pick up the energy from the device reading, like proper passive RFID.
