Being a Samsung Pay user, I really appreciate how convenient it is to summon the app when I'm about to pay or need to show my membership card to the cashier. Indeed, a simple swipe up from the lock or home screen brings up my wallet. Apple and Google have taken a different approach, where their payment software is automatically launched when you place your device near an RFID reader. However, iOS users can also double tap the power button to bring up Apple Pay, which is — at least in my opinion — more convenient, as it lets you choose the card you want to pay with before completing the transaction.
