Several Media of Gossip Application in Parking Lot Management System - Tigerwong

In recent years, the parking lot system technology has developed rapidly, and the applied management media are more and more advanced, such as the mainstream non-contact IC card, RFID tag card, license plate, etc. However, you may not have seen the management media used in the early parking lot system. This time, we will introduce some media used in the parking lot system. You can understand the development process of the parking lot system through these. 1. Paper magnetic card paper magnetic card is the first medium to appear in parking lot management, which appeared in the 1970s. It still has many advantages, such as low cost, small volume, flexible design and so on. However, due to technical reasons, the paper magnetic card has small storage capacity, is easy to be damaged, and the data cannot be encrypted, which leads to its elimination by the market. 2. At present, bar codes are also used in the license plate recognition parking lot system. It has low cost, large ticket box capacity and can meet high-capacity invoices. It is suitable for use in some parking lots with more temporary vehicles. Its disadvantage is that it can only be used once and cannot be rewritten. 3. Contact IC card IC card is an integrated circuit chip technology, which is a great progress compared with magnetic card. The data can be stored encrypted, with large storage capacity, durability, simple maintenance, and one card can be used for multiple purposes. However, its disadvantages are also obvious. For example, when it is used, it needs to be inserted into the card slot of the card reader, which is inconvenient to use, and it is easy to be damaged due to the exposed contact. 4. Radio frequency card radio frequency card combines radio frequency identification technology and IC card technology to solve the problem of contact card swiping of other cards. It is a new technology developed in recent ten years. Non contact IC card is a kind of radio frequency card. The radio frequency card is easy to use and operate, does not need to touch and swipe the card, and is suitable for use in the parking lot. Moreover, it has high reliability, stable performance, high security factor and good encryption performance. It is one of the commonly used media in parking lot system at present.
