For card insertion touch the power, there is life is short, the system difficult to maintain investment in infrastructure and other shortcomings, but early development. * Contactless smart card, also known as radio frequency card, in recent years developed a new technology. It succeeded in radio frequency identification technology and IC card technology together, will have a microprocessor integrated circuit chip and antenna packaged in a plastic substrate being. Reader using magnetic induction technology, through wireless way to read and write in the card information and the use of high speed half-duplex communication protocol. The advantage is long life, wide range of applications, easy to operate, fast, but there are high costs and write complicated equipment susceptible to electromagnetic interference and other shortcomings. Currently, the effective read distance contactless card is generally 50 ~ 200mm, far reading distance of up to several meters (used in car park management system). * Non-contact IC card function is strong and varied. As businesses, community, campus and hospitality increasingly concerned about the use of non-contact IC card, making it clear that many of the new areas of non-contact IC card, while the bar code, magnetic card system is also due to the inconvenience, easily damaged and other reasons, faces Fate replacement. 3, non-contact IC card Features: * passive, non-contact-free operation and long service life. * Data exchange from the media except radio shielding effect, easy to use. * Waterproof, dust-proof, anti-static interference, adapt to harsh environments. * Sensing distance, generally up to 5-15cm * Safe and reliable, the chances of misreading or not the reader is almost zero, tens of billions of passwords, unable to decipher. * IC card loss is very simple.
