What should I do if my card is not recycled?

You can cut out the card if the bank doesn't recycle it. But remember a few key points: Confirm with the bank and cancel the card completely. The back magnetic strip should be cut completely: cut completely from left to right. A single cut in the middle is useless. Personal information can still be read. Personal signature, cardholder's name part to be painted or cut out separately, throw away. The card number part had better also cut open. If it is PBOC 2.0 IC card (with both magnetic strip and contact IC card), it needs to destroy IC chip at the same time As for the following schemes: Burn off card: the PVC material of magnetic card adds flame retardant commonly, so combustion has certain problem. Strong magnet degaussing: at present, there is a widely used magnetic card technology, called "strong anti-magnetic". It has certain protective ability to magnetic field, so it is not safe. If you find my article very helpful and interested in me, you may

What’s the difference CPU card,IC card,ID card?

Their definition As for the difference CPU card, IC card,ID card, let’s understand their definition first. In a broad sense, IC=integrated circuit= integrated circuit card Want card to have integrated circuit only (chip), can calculate IC card actually. ID card also calculates. However, we often hope that the chip in the card cannot only record an ID number, we also hope that the chip can store information, do some encryption and decryption calculation or even logical operation. At this point, we can narrowly define the former is an ID card, the latter is an IC card. Among them only hardware encryption and decryption ability, we call it the logical encryption card, have the logical operation ability, we call it the CPU card. That definition out of the way, let’s move on to the physical structure In addition to the substrate and chip, the main is the antenna. According to the interface points, cards can be divided into three types, here we a
