The difference between ID card and HID card

ID card refers to a read-only card containing EM chip or other chips, with a frequency of 125KHZ. Widely used. He can only read serial numbers and cannot write anything inside. The ID card reader is currently the most widely circulated card reader on the market, with multiple transmission formats and almost universal capabilities.

HID card is a type of card reader and card brand in the United States. It is just a product brand and has little to do with ID. However, it is also a type of ID card. Its chips are set with serial numbers and encrypted by region, so it has a custom format and cannot be used with other brands of card readers. In other words, HID cards can only be used on HID card readers.
