Proximity Card

 Proximitycard is also called contactless IC card and also known as radio frequency card.It’s composed of an IC chip and an inductiveantenna and sealed in a standardPVC card, the problem of non-source and contact free can be solved by combiningthe technology of radio frequency card with IC card.

Features:

1,Highreliability. No mechanical contact between the card and reader, which can avoidvarious failures caused by rude card inserting, other objects inserting besidescard, dust and grease. No chip can be seen on card surface, no chip drops, staticelectricity breakdown, bending to damage and other problems; Convenient tooperate. The card can be operated within effective range; Directionlessimproves the reading speed.

2.Anti-collision (can distinguish automatically), radio frequency card comes withanti-collision mechanism that can prevent interference between data, reader andwriter can handle multiple proximity cards at the same time.

3.Wide range of applications. The structural characteristics of memory of radio frequencycard make it applied to different systems, different passwords and accessconditions can be set by user according to different applications.

4.Good Encryption performance, two-way authenticationmechanism, operationalpasswords and access conditions are required for each sector.

Mainchips to be used for proximity card:

Philip:Mifare1S50/Mifare 1S70/ FM11RF08/Desfire　Infineon: SLE66R35/Legic Huahong: SHC1104　ShanghaiFudan: FM11RF08　ATMEL:AT88RF080/Temic:e5551 proximity IC card/EM　Swiss Microelectronics: EM4100/4102

Applicationsof proximity card:

Proximity card is widely used inidentity card, education card, social security and health insurance card, buscard, fuel card, highway, road and bridge toll, parking card, smart card for communitymanagement, attendance card etc.
