I love the idea and design of this; it's beautiful. But using storage-only NFC tags as an authentication token? This is not a good idea.

  Watch the video that covers security, it should hopefully explain why we do it that way. Thanks

    What about shaking hands with people? The video really didn't convince me it was secure. You use the bottom of your hand to, for instance, hold stuff - so what if someone passed you a phone configured to scoop up data?

    I'm afraid I think that video just misrepresents how ISO14443A anti-collision works. Most reader devices (like phones, door locks, etc.) will select the tag with the best signal (usually = the closest) and deselect others during the anti-collision protocol. This /doesn't/ rule out a malicious reader selecting the other tag, subject to being able to power it.

      Try that in reality and see how it works out for you.
