Android 6.0 Android Pay
Similar to Apple or Samsung Pay, Android 6.0 has a new feature called Android Pay. It's similar to Google Wallet, and essentially will let users add a credit or debit card to their phone, and make wireless mobile payments with their phone instead of carrying around a wallet. Simply set it all up, unlock the phone with a pin (or a fingerprint) and quickly make payments with your phone. Here's more details about Android Pay and how it compares to Samsung Pay, but either way you'll want to use it. It's extremely convenient.
