Induction ID cards thick, thin card -TK4100 Chip
ID card induction ID card induction ID card ID smart card ID card ID card attendance RF
After the ID card, also known as radio frequency ID card, a read-only non-contact IC card, which is read by the reader inductive powering and unique card number stored in the EEPROM chip, card card write-once before the closure, seal cards You can not change. Passive and avoid contact with the two most prominent feature chip RF interface circuit is a critical core technology, which receives RF energy from the reader, to generate power and clock chip, and using phase shift keying and load amplitude modulation technology for wireless communication between the card and reader. non-contact ID card is easy to operate, fast, reliable, and other advantages, has been widely used.
ID Card Type:
1, thick card: thickness 1.8mm, thick card ID card number can be sprayed in various formats can be screen printing, you can print stickers or after additional color transparent film posted up costs low, is the world's. economical RF ID card.
2, the standard thickness card: the thickness of 1.05mm, can be double-sided color offset printing, printing photos, you can print within the ID cards of various formats of laser or self serial number or code.
3, the standard thin card: thickness 0.9mm, you can double-sided color offset printing, printing photos, you can print within the ID cards of various formats of laser or self serial number or code.
ID card common technical parameters:
1, the operating frequency: 125KHz
2, the internal serial number: 5 bytes
3, sensing distance: 5-300px
ID card Main features:
The carrier frequency is 125KHZ (THRC12) or 13.56MHZ (THRC13);
Card reader to transfer data to the modulation scheme to load amplitude modulation;
Card data encoded using anti-jamming ability of the BPSK phase shift keying;
Card reader data transfer rate to 3.9kbps (THRC12) or 6.62kbps (THRC13);
Data storage using EEPROM, data retention time more than 10 years;
64 total data storage capacity; including manufacturers; distributors and user code;
Card number can not be changed before and after the closure card writing, the only absolutely sure that the card number and security;
ID Card Applications:
Non-contact ID card is especially suitable for high traffic situations Typical applications: Dining Hall frequency identification system, the Patrol System, time and attendance systems, access control systems, parking systems, business card system typically used for security demanding occasions.
Class quality; class service; is our eternal pursuit!
