ID card
     ID card full name for the identification card (Identification Card), is a non-writeable proximity card, with a fixed number, mainly Taiwan SYRIS EM format, the United States HIDMOTOROLA and other types of ID cards. ID card and magnetic card, just use the "card number" only, the card in addition to the card number, without any security features, the "card number" is open, bare. So ID card is "induction magnetic card." ISO standard ID card specifications: 85.5x54x0.80 ± 0.04mm (H / W / thick), the market there are some thick, thin card or shaped card.
        ID card in the weak system is generally used as access control or parking system user identification, because it does not have built-in power supply, when used without contact and long life, so weak in the system has a wide range of applications. The emergence of ID card basically eliminated the early magnetic or contact IC card. But because the ID card can not write user data, the record content only card number can only be written one-time by the chip factory, developers can only read out the card number to be used, can not be based on the actual needs of the system to develop a new number management system. At the same time because the ID card has no content, so the card holder's authority, the system function operation to completely rely on the computer network platform database support.

In addition, the industry is now the basic consensus is not suitable for ID card made of card, not suitable for consumer systems. ID card can not do the biggest reason for consumption is the "credit" problem. Because the ID card without key security authentication mechanism, and can not write card, so consumption data and the amount can only exist in the computer database, and the computer is managed by personnel, from the truth and the mechanism completely exist cheat space, , In case of computer problems caused by the consumption of data loss, there will be disastrous consequences. Therefore, to make consumers agree with the community management ID card authoritative (ie credit) is impossible, too much money disputes can only ID card consumption system can not be used.
