I remember rolling my own authentication system using an iButton back in college. I had it mounted on a key fob. Worked pretty well, you touched it to the reader and typed in a 4 digit PIN. Don't really understand why these didn't take off vs. a smart card for authentication: as far as I know they're more durable and they're pretty cheap. |

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?
