[Gear] How secure is Samsung Pay on the Gear? Without a fingerprint scanner, how can I be sure someone won't use my credit or debit cards if I lose my watch?

• Samsung Pay on Gear protects your card information with the advanced security by using tokenization, KNOX and PIN protection to make secure payments. Cards data is synced to Gear from your mobile deivce via a secured Bluetooth channel. 
• You will need to setup PIN when you activated Samsung Pay on your Gear. You must enter your PIN each time you put on the Gear, and you won’t need to enter your PIN again until you take your Gear off.
