Proximity Card

 Proximity card is also called contactless IC card and also known as radio frequency card.It’s composed of an IC chip and an inductive antenna and sealed in a standard PVC card, the problem of non-source and contact free can be solved by combining the technology of radio frequency card with IC card.

Features:

1,High reliability. No mechanical contact between the card and reader, which can avoid various failures caused by rude card inserting, other objects inserting besides card, dust and grease. No chip can be seen on card surface, no chip drops, static electricity breakdown, bending to damage and other problems; Convenient to operate. The card can be operated within effective range; Direction less improves the reading speed.

2.Anti-collision (can distinguish automatically), radio frequency card comes with anti-collision mechanism that can prevent interference between data, reader and writer 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 authentication mechanism, operational passwords and access conditions are required for each sector.

Main chips to be used for proximity card:

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

Applications of proximity card:

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