It is not a new story that RFID applied into the access control sector. The earliest RFID technology that emerged in Access control setor shall turn back time to mid 20th century, And it was first introduced at low frequency of 125 khz, with a unique ID number inside the chip. EM4100 chip, as one of the most typical chips, emerged in this stage. It brought a hurricane to the traditional access control sector, which the traditional physical keys were gradually replaced by a piece of card. It not only brings convenience but also maintain high security.
Glory of ATT5557 chips in access control system
While as technology developed, the traditional EM4100 chip is no longer worked well, because the ID number could be easily duplicated, which make its safety severely be doubted. Then ATA5557 chips emerged in the stage, it is a chip with pin code embedded, which allow user to set up the password for safety concerns. To better protect the password, this T5557 chip also adopt a interesting settings, which if the password misread for over 3 times, the chip will permanently locked and can not be used any more. The market’s response is so appreciated that access control systems based on T5557 chips rapidly occupy the market.
Lord of chips for NXP Mifare 1k s50 chips
Time turns to 21st century, NXP mifare 1k chips, which worked at high frequency of 13.56 Mhz whipped up a thunderstorm. It was no longer merely bear UID code or passwords, it extended the multiple functions, up to 1kB memory organized in 16 independent sectors, each sectors could sets an application and its passwords. It is amazing function, which make multiple applications in one card possible, beside it contains a logical counter, which allows it able to conduct plus and deduct algorisms. It was so popular as if all the RFID cards bear this Mifare 1k chip in one night. It is still the most welcome chip in the market.
New Emperor- NFC mobile phones and bio technology in access control
Early at year 2005, Nokia have published its NFC mobile phone, which could conduct the same functions as Mifare 1k s50 chip does. This emerged NFC technology though is fantastic, it is not accepted by user’s then. In 2007, Apple launched innovative Iphone, which completely overturn the whole phone sector. And this impact also affect the newly born NFC technology, the Andriod Mobile phone is the first mobile that publicly support NFC technology. By using this technology, NFC that used in Access control is gradually into reality.
Advantages of RFID in access control
Contactless identification with limited read distance. Just a simply touch will the card be indentified. Limited read range also provide user protecting their user’s data and prevent unwanted operation
Access control data management. RFID technology help users more efficiently manage visitor’s access data, such as vistor’s profile, password and access authority through relevant RFID software. Time attendance system is based on this idea.
Security . RFID provides reliable security features either by its unique ID and password or by its encryption algorisms. Especially when advanced DES and 3DES encryption algorisms introduced, user data by nowadays technology is impossible to break.
