One of the problems of working in tech is it can get annoying when you see lots of money being spent solving the wrong problems, or implementing completely ineffective solutions. Take credit cards and RFID, for example. There’s a big push in the US to include RFID in every card. I’ve had a card with RFID for just over a year now. The benefit to me? Theoretically, I can hold the card against the card reader, instead of having to swipe it through the slot.
