Several kinds of media gossip application in a parking lot management system

Technology developed rapidly in recent years, the parking lot system, the management of the medium is becoming more and more advanced, such as the current mainstream of non-contact IC card, RFID card, license plate, etc., these are all familiar with.But early parking system application management medium you might not have seen, this time we have for some used medium introduce parking lot system, we can through these to know the development process of parking system.
1. The paper card
the paper card is the medium of first appeared in the parking lot management, in the 1970 s.It still has many advantages such as low cost, small volume, flexible design, etc., can satisfy the large capacity of hairpin.But due to technical reasons, paper card storage capacity is small, easy to damage, unable to encrypt data, etc., cause its was eliminated by the market.
2.
bar code on the bar codes are used in the parking lot management system, its low cost, large capacity of ballot boxes, can satisfy the large capacity invoice, suitable for more temporary vehicles in the parking lot.Its defect is one-time use only, cannot be changed.
3. Non-contact IC card
IC card is a kind of a kind of integrated circuit chip technology, relative magnetic card, it is a great progress.Its data can be encrypted storage, large storage capacity, durable, easy maintenance, and can use a card.But its shortcomings are obvious, such as when it is used to insert the card reader of the plug bayonet, use inconvenient, and due to contact the leakage, is easy to damage.Rf card
4.
rf card is combined radio frequency identification technology and IC card technology, solved the difficult problem of other card class needs to access card, is a new technology developed in recent years, contactless IC card is a kind of radio frequency card.Rf card use simple operation, no contact card, and is suitable for use in the parking lot.And it has high reliability, stable performance, high safety coefficient, encryption performance is good, is currently one of the parking lot system commonly used medium.(http://www.nthuanli.cn/)
