Nice execution. I saw several pitches for unifying cards while working for a VC.
As a consumer I have a few suggestions:
1. Make the card switch/activation button detect the fingerprint of the owner. (The merchant or waiter sliding the card could press the button accidentally and switch to a different card)
2. Show me that a tap-scanning tool can't take the data for all of my cards. (from hackers to accidental taps)
3. Can a magnet disable this card?
4. What happens if someone steals my coin? Can I disable it remotely with the app? Can it happen automatically?
3 and 4 were answered in their FAQ - a stronger than average electro magnet will break Coin, and Coin is automatically disabled when it's out of range of your phone.

Good luck!
