The bus card of Beijing office was accidentally broken, and the card number on the card disappeared because of its age. Go to the designated bus to return the card, saying that you can't return it, but there is still a lot of money in the card. Let me give you an answer. I have some research on this. First of all, I tell you that the bus card is not a magnetic card, but a coil is attached to the outer edge of the card. The chip coil is connected to the middle position on one side of the card as an antenna. In order to induce the signal chip in the card reader to record information (including balance consumption records, etc. ), the bus card is most afraid that the folded chip is not easy to be damaged, but the card is often folded and the coil is easy to break. A broken coil is equivalent to a broken antenna, and the card reader can't read the information inside, so the solution is to find out where the card is broken or folded. If you can see where the card is broken or folded, you'd better do it. Try to bend the broken part of the card on his card reader and look at the computer screen until the information is displayed. If you can't see where the card is broken, try to read the card information by bending the four sides (because I am an insider, hehe) and tell you. A card is the same as a one-way subway ticket. One-way tickets look thin, but they can be layered. Divide the one-way ticket into two layers, exposing the coil inside. You can study it first.
