Please elaborate, including the principles, equipment and other aspects of knowledge
RF IC card and card reader is a non-mechanical contact between, so the RF IC card is particularly suitable for large flow through the access control system. Radio frequency IC card and card reader between the use of radio communication technology to communicate, and radio waves are open in space, it is easy to be intercepted by the external, so the general CPU-free logic encryption IC card can not resist the most simple password attack , The communication content is easy to be stolen, tampered with and fake copy, etc., its security is not as good as ordinary logic encryption contact IC card.
Inductive technology, or radio frequency identification (RFID) technology, is a way to read information on a card without direct contact between the card and the card reader. The use of inductive card reader, no longer because of contact friction caused by card and card reader equipment wear and tear, no longer need to plug into the hole or in the magnetic slot, the card only in the card reader card range Can be.
Smart cards (Smart Card) are often translated into "smart card", "smart card", there is another called called IC card (Integrated Circuit Card). Generally refers to the card embedded in the integrated circuit chip, you can use the chip integrated circuit memory unit, to carry out data storage and some corresponding data processing.
