We had these for the EE department doors in college. They were pretty cool. Nowadays I don't want another key. I want a standardized RFID protocol (active and passive). I have two office RFID cards, a key-fob for my car, a card for the garage, my phone supports NFC and I get another card when I go to a hotel. And they are all different and incompatible. I can't keep both of my office cards in my wallet, because while they are not the same protocol, they are on the same frequency and conflict. It is maddening. I want my phone to act as an active NFC identity transmitter, and I want a backup passive RFID card I can put in my wallet. It should be simple to pair these two devices with all of these desperate systems. Oh, and while I am at it, can my phone not be a whore about it and only respond to receivers that I have expressly authorized. Why is standardization so hard?
