It’s time for a customer to pay.
Customer: “I don’t have my wallet, but you do have my card info, so we’re fine!”
Me: “Huh… we don’t have that information.”
Customer: “The card terminal stores all info! Wake up and listen to some intelligent TV!”
Me: “That terminal doesn’t hold card information. If it did, it’d be a hacked terminal.”
Customer: *She’s hitting it with the tip of her fingers.* “That terminal stores every card. I only need my PIN, and It’s okay! Ring up my total, I’ll show you!”
I get the terminal ready to accept payment by card. It displays the total and simply says “insert card/enter PIN”.
Customer: *Enters PIN.* “Why is nothing happening?”
Me: “Because it needs the card inserted first.”
Customer: “But it should have all my info!”
Me: “So the machine should know who you are?”
Customer: “Yes!”
Me: “Okay, please tell it who you are.”
Customer: “…”
Me: “…”
Customer: “It should know who I am from my PIN!”
Me: “So if a customer has the same PIN, they can use money from your account?”
Customer: “…No!”
Me: “So how will the terminal know which bank account to take it from?”
Customer: “Look, I don’t get how it all works, but I saw this on TV, and you don’t need my wallet anymore! It should just know who I am!”
Me: “Did these customers do anything else? Like tap their phone instead, or maybe a watch?”
Customer: “Yes, I saw them tap a watch, but that’s just stupid! Who would pay for their groceries using a watch?!”
Me: “I can think of stupider things…”
She ended up paying cash…
