The card has two token security, and holds your signature as well. To top it all off, only the last four digits of the card number, the expiration date, and the card name you choose show up on Swyp’s screen.
Since the card is linked to your phone, it literally does not work unless it’s within a certain distance from your phone. If someone steals your card without the phone, it’s a useless piece of plastic. Additionally, the card is sealed with a PIN, so if someone enters that number incorrectly many times in a row, Swyp will wipe all your information from the card immediately.
