In an email to people who have ordered Coins, a few questions have been answered:
- You will be able to reactivate your Coin even if your phone is dead by tapping in a "Morse-code-like" password using the button
- Coin will track how many times your card is being swiped and tell you if someone is using it when it isn't near you
- Coin can "auto-lock" based on proximity such that you can swipe, but cannot change the card that is selected -- so a waiter or waitress can't accidentally switch your payment method when you pay your bill
