Card.io will scan cards and OCR them. Maybe they do something like this to ensure the name matches the registered name on the account? https://www.card.io
Edit: And it's on the magnetic data, too.
Couldn't you technically bypass the OCR by taping a piece of paper with a different name or number over it? Does the magnetic data store the name?
I go by my middle name, but some places have forced me to use my first name, so my cards are a mix of my first+last and middle+last name. So then I would look like two different people to this coin wallet?
The magstripe data has all the name information in it.
Swiping a card passes along the name on the card.
But a waiter doesn't ask for ID when taking your card... so even if the Coin identifies you as John Smith when you pay your check, the fact that you are Steve Jackson who presented the card doesn't mean anything. And you can have multiple cards with multiple names in your Coin.
I believe the coin app will only put cards on the Coin that match the name that is on your account.
