Many credit, debit, and gift card systems are moving away from magnetic strips and into embedded chips. The transition isn’t going smoothly at all. Everyone I know who uses a chip card has encountered problems. Even one person who does not have a chip card ran into problems when every card reader in Europe required a chip. It’s like this:
Have you changed to the chip-type cards yet? How’s that working out for you? -Thanks, Carl Baker!

I do have fun when the cashier apologizes for the extra time they require to read. I tell them that I understand, since the chip contains a photon that is quantum-entangled with another photon at the National Institutes of Standards and Technologies in Washington, DC. The extra time taken is because the quantum state of both photons are being compared, to ensure that both are identical.
I further 'explain' that in Europe, entangled photons are in Saint Cloud, France, where the International Standard Kilogram is stored. The British, of course, keep theirs at the Royal Observatory.
Once all retailers in America are able to use the chip reader, and once (or, "if") it starts going a lot faster, then no worries. Until then, it's just an annoyance for everyone involved, cashiers included.
