The Payment Experience
With at least one credit or debit card’s detailed entered on your mobile app of choice, here’s how you’d use them when it’s time to pay:
Apple Pay: Take your phone out of your pocket, rest a finger over the Touch ID sensor (without pressing down), and hold it over a contactless payment terminal. The iPhone uses Touch ID to authenticate your fingerprint and immediately processes the payment. Touch ID makes this more convenient as you don’t have to unlock your phone first.
Google Wallet: Take your phone out of your pocket and hold it over the reader. You may then have to enter your Google Wallet PIN, which is supposed to be different from your phone-unlock PIN for security reasons. Where Apple Pay uses your same fingerprint at the terminal, Google Wallet requires your phone have two different PINs —
it’s just clunkier. At least you don’t have to open the Google Wallet app first.
These payment methods need to be as convenient as possible because they compete with a piece of plastic that can be swiped or inserted everywhere. In many non-US countries (like Canada), you can tap your plastic credit card on such readers all over the place. Of course, this doesn’t give you any fingerprint or PIN security. That’s why contactless payments have traditionally been limited to smaller-value purchases.
