ID card

1, ID Card Features
• TK 4100/4102 standard card Inductive ID
• Chip: TK4100 Standard Chip
• Operating frequency: 125KHZ
• induction range :8-20cm
• ID card thickness: thickness 1.8mm, standard card size, is the most economical with the ID number of the radio frequency card, with a portable hole, can be screen printed text information;
• Standard Thin card: thickness 0.8mm, standard size, you can offset printing, screen printing, printing photos;
• Non-standard thin card: the thickness of 1.05mm, the standard size can be offset, screen printing, printing photos;
• Typical applications: patrol system, attendance systems, access control systems, business-card system and other areas of radio frequency identification
2, ID card introduction
It is powered by reader and read out the sensors is stored in the EEPROM chip, the only card number, card number, before the write-once the sealed card, seal card can not be changed. Passive and avoid contact with the chip, the two most prominent characteristics of RF interface circuits is a critical core technology, which receives RF energy from the reader, in order to generate power and clock chip, using phase shift keying and load amplitude card and reader technologies such as between the wireless communication. ID card with a user-friendly, fast, reliable and outstanding advantages such as access to a wide range of applications.
3, ID cards Key Features
• carrier frequency of 125KHZ (THRC12) or 13.56MHZ (THRC13);
• card reader to transfer data to the modulation method for the load amplitude modulation;
• card data encoding using anti-jamming ability of the BPSK phase shift keying mode;
• Card reader data transfer rate to 3.9kbps (THRC12) or 6.62kbps (THRC13);
• Data is stored using EEPROM, data retention for more than 10 years;
• Data storage capacity of 64, including manufacturers, distributors and users of code;
• card number card before the closure can not be re-written after the changes, make absolutely sure that the only card number and security;
• T HRC13-chip addition to package into a standard card shape, the application needs can be packaged into a chip according to a variety of shapes.
4, ID card works
System consists of cards, card readers and back-controller
1, readers will be the carrier signal sent out by the antenna;
2, the card reader into the work area, by the card in the inductor coil and capacitor resonant circuit consisting of the carrier signal emitted reader to receive the card in chip RF interface module to produce the resulting signal power supply voltage, reset signal and system clock, so that chip to activate;
3, chip control module will read the data in the memory is encoded by phase modulation in the carrier modulated by the card reader to give back to the antenna;
4, the card reader docking received loopback signal demodulation, decoding, sent to the background after the computer;
5, the background computer, according to the legality of card number, for different applications and make the appropriate treatment and control.
5, purchase and use instructions
1. This company has contactless IC card, M1 card, CPU card, ID thick card, ID card thin, long-distance cards, shaped cards, key ring cards, white cards wholesale;
2. The card you should keep, keep clean, do not distort, to avoid sharp objects scratching and wear;
3. Please stay away from electromagnetic fields and electrostatic zone, to prevent the high-temperature, high pressure, and avoid going near corrosive substances;
4. For non-contact IC card can be encrypted using the process to change the factory password, the password must include the time to return the card, or vendors can not test treatment;
5. Returned IC card, please indicate the reasons for withdrawal card read-write device models, the use of the environment and problems, if necessary, please attach the read-write device for us to test the card;
6.IC cards and CPU cards have the default factory password is factory password, please change your password carefully, non-professionals do not arbitrarily change the password, many errors would cause the card is damaged;
7. M1 card to buy my company, my company complimentary password to modify the software, we do not carry change password with caution;
8. All cards are original cards, white cards go directly to the wholesale goods, wholesale agents are welcome to purchase;
9. If the card is provided for products, such as special-shaped card and key chain cards, coins, cards please contact the company related personnel.
