The RFID tag is made of high temperature and solvent resistant material and can be applied by cord or clamp. Particularly suitable for identifying garments, products and components in production and logistics environments. It also allows the protection of the brand and the limitation of counterfeiting in branded products and original spare parts. TK4100 RFID chip read only LF 125 KHz memory 64 bit.
APPLICATIONS - Public transport tickets - Clothing identification labels - Loyalty cards/ Fidality Card - Attendance - Safety systems - Access control - Vending systems
TK4100 is powered by an external coil in an alternating magnetic field and obtains the clock through one of the two contacts. The other contact of the coil turns the modulation current on and off; the chip sends 64 bits of information from its pre-programmed memory during manufacturing. In the TK4100 chip, data is modulated and transmitted with Manchester-encoded formatting. Chip programming is done with fusion lasers on polysilicon to store a unique code on each chip. The continuous output data string contains 9 leading 1 values, 40 bits, 14 parity bits, and 1 stop bit. No buffer capacitor is required because the control logic has very low power consumption. Only one external coil is needed to operate the chip. The parallel resonance capacitor of 74 pF is integrated into the chip.
