I think it's ridiculous. It takes no time to take out my wallet, pick a card and swipe. You guys have to take out your huge phone, fingerprint unlock, then open an app then point to the machine? No thanks. If you gotta type a pin to open your phone, then you can type your pin on the machine.
I prefer cash anyway. I'm not a fan of fingerprint readers either. I'm not even old.
Again, as I stated before, people who call it "ridiculous" don't actually use it, so have no clue as to what they're talking about. I often times ALREADY HAVE my phone in my hand when at a register/line, so it would actually take MORE time to set it down and pull out my wallet. And if I did not already have my phone in my hand, it would equally "take no time" to pull my phone out instead of my wallet. Next, the Galaxy S7 is hardly "huge," and the app does NOT have to be opened, nor the phone "fingerprint unlocked." You literally swipe up from an off screen, and touch your finger to the home button. Then you're done. How in your head that process is somehow more time consuming than pulling out your wallet, pulling out the credit card you want to use, or searching for and counting out the amount of cash you need, giving either to the cashier, having him count the cash or swipe your card, wait for it to process, wait for a receipt to print, have him hand you the receipt to sign, you sign it and return it and the pen if you used a credit card, or wait for him to put the cash in the drawer and print a receipt and hand it to you, is beyond me.
Also, it comes in incredibly handy for times, like wen I go to the gym, and don't want to bring cash or credit cards with me, but may need to make a purchase on the way there or on the way home.
Finally, you DON'T have to type a pin to open your phone.
