Wait, can I use my 'Dial-Up' protocol to pay for things? That would be a real throwback!

4G protocol? What is this, a teleportation exam? I'll stick with NFC, the contactless payment solution.

RFID, really? I thought that was for tracking inventory, not making payments. This exam is tricky!

Hmm, Bluetooth? Isn't that just for connecting my headphones? I don't think that's the right answer here.

Near Field Communication (NFC) is the answer! That's how I can tap my phone to pay for things at the store.
