1) Better security
2) Much faster
3) Supports all your cards
4) It's a bit of a status symbol
5) Don't have to bring your wallet
Um... Status Symbol?!?!? Rap songs are litmus test for whether something is a "status symbol", and nobody is going to brag about payment methods or make it rain iPhones or sing "I whip out my phone to ApplePay ya, cuz all y'all know I be an ApplePlaya"
(Also, where exactly is your wallet that you don't bring it with you? Because if it's in the car then your security level just fell 9000%)
