NFC is enabled, but I can't get any of the half dozen or so apps to actually read my bank card with the "money pass" and "Plus" symbols or my Sonitrol RFID security card. I've tried GBV RFID Validator, NFC Retag, NFC Basic, NFC Tagcontrol, NFClassic, and a couple others that had poor ratings. There's a YouTube video showing a guy using Retag, and tons of reviews of a bunch of these apps are people saying it worked for them. I'm at a loss. Any ideas?
