  • RFID/ NFC-Reader /// App to confirm blocking

Does anyone have experience with a good app to test how good a RFID blocking is working?
And what data can be openly read if a NFC signal is ca(t)ched?
(Context:

  1. simply to test if a product does what it promises
  2. I have a card which shouldn't have NFC (activated) but I don't trust the provider)
