BLE is not RFID!
Can you reinterpret RFID to be Near Field Communications (NFC) ? It’s an ISO standard.
75 cent RFID tags with memory.
My HTC one and most new cell phones nave an NFC reader built in. I have NFC tags, size of a quarter, adhesive. I stuck some on the tops of wine collection in cold storage bottles. My phone will interrogate, read, lookup photo of wine bottle label, lookup in Evernote as a database. No code.
But NFC is 1 inch or less. Arguably not RF.
Some tags use inductive fields, not efields and in RF. Cheapest.
