Contactless payment options include Apple Pay, Android Pay, Samsung Pay, and Microsoft Wallet. Apple Pay uses NFC and Touch ID on iPhones 6 and above, storing encrypted payment details. It was launched in 2014 and allows adding cards through Passbook or manually. Android Pay is similar but works on Android 4.4 or above. Samsung Pay can work through magnetic card readers or NFC. Microsoft Wallet failed to gain popularity. CurrentC uses QR codes and was developed by retailers to avoid credit card fees, but offers less fraud protection than cards.
