    You have the NFC portion missing the coolest part of the technology. The card uses induction to charge and power the chip and the chip getting the electricity powers up and THEN it will send it's signal through radio waves specifically 13.56 MHz.
    I don't normally correct people but with this I just thought how cool it was to know they power up through induction so I had to share it with the class. Amazing video though.

      In the summers of 1969 and 1970 I worked the evening late shift at a Sunoco station in Maryland. We had about 50/50 cash and credit card. We used a multi-part form (light card, carbon paper, thin paper on top and a clackity swipe machine to imprint the card's raised name and numbers on the form. I wrote the price, license tag and date by hand, then gave the customer the paper copy. The owner's bookkeeper had to collate, add up and submit the card copies for billing, etc. Lots a manual steps and unavoidable errors, etc. Stone age, really.

    It was a Frenchman (Roland Moreno) who invented and patented the chip card in 1975. The French were therefore the first to have one.
    American banks refused to pay royalties. If Americans have chip cards now, it is mainly because the patent has expired.

    I always expose my card strip to a strong magnet, rendering the strip useless. It makes it so skimmers don't work. Only problem is I can't use it in an ATM or some parking pay stations, for which I keep one card only for those purposes, attached to a small account with very little money to steal.

    Before there were magnetic strips, the card was run through a device that physically imprinted the numbers on a two-part receipt, similar to a mimeograph machine. At the end of the day/week/month, the store's copy of the receipt was sent to the credit card company or bank. That made it quite easy for people to exceed their credit limits.

    Probably not necessary, but one of the biggest changes was the move from imprint machines to swiping the cards. I was in retail when we had to run the physical card through the imprint machine onto a voucher. This imprinted the information from the raised letters and numbers on the card, and then you had to call the card company to get an authorization number for the charge. It's somewhat amazing that the raised letters and numbers on the plastic cards are just now starting to disappear. Nice Video!

    As for the rest, a few technical details were maybe a bit off, but worth it to have such a complete story told.

    Very nice! I'm from Costa Rica and I actually saw this timeline happening in my country. First swiping, then contactless cards and now the phone. Here nobody uses cash anymore.
    And also we have a new system by which you link your phone number to your bank account. So I can transfer you money, regardless of your bank just by knowing your phone number. So even if you are in a remote place in the country, as long as they can give you wifi or a hotspot youncan pay them.
    The last big thing that continued using cash was public buses. And this year they started implementing dataphones, so practically people won't need to use cash anymore.

    FYI smart card NFC works differently compared to how your phone talks to stuff, such as with bluetooth. Your phone creates its own radio waves to talk with other devices and powers itself. It also has its own receiver so it can talk both ways. The smart card instead enters the field generated by a card reader, powers itself through electric induction, and then modulates the existing field created by the card reader, which the reader notices and extracts data from. Its also different from RFID, which is like how your car easy pass works in toll roads. Just a small correction.

    In India, cards were limited to a small section of salaried individuals, that had financial literacy
    Around 2016-17 the govt. demonetized the big bills (which was 80% of the cash by value) so everyone got a taste of contactless payments (via mobiles), which was further accelerated by covid lockdowns
    There's also an age factor, young graduates can apply for a card after they get a job (age 22-23) whereas for contactless payments one just needs to have an account in the bank (age 18)

    You forgot the stage when cards were embossed and retailers would roll over the card with carbon paper to copy the credit card number onto paper. The buyer would then sign the piece of paper.
