TK4100 Chip Card

Good products speak for themselves. Xinyetong TK4100 Chip Card has been exported to Southeast Asia Africa, Central America, South America, North America, Western Europe, Southern Europe, Mid East, Oceania, Northern Europe, Eastern Europe South Asia, Eastern Asia.

Xinyetong TK4100 Card can be made into a white card or a color card and we can also provide customized products for you, such as color, size, style, etc.

Don’t worry about the chromatic aberration of our TK4100 card. We use the high precision colorimeter to ensure the consistency of end products and samples.


TK4100 Chip Card is a kind of read-only contactless smart card , working on 125KHZ frequency. It does not require a built-in power supply and can use without contact and has a long service life. TK4100 Chip is completely compatible with EM4100/EM4200, and they are very similar in performance and usage. What is the difference between the TK4100 card and the EM4100/EM4200 card? Compared with the EM4100/4200 card, TK4100 chip card is much cheaper and very competitive in price.


TK4100 chip card is often made of PVC or PET material and the size of a standard TK4100 card is 85.5mm*54mm. The TK4100 chip plays a central role which directly determines the performance and function of this card. TK4100 is a CMOS integrated circuit for using in 125 kHz read-only RFID cards. It is compatible with EM format. TK4100 chips data modulating and transmission is coded by Manchester modulation format. The programming of the chip is performed by laser fusing of polysilicon links in order to store a unique code in each chip. No requirement of buffer capacitor for low power consumption of logic control core. Other features as follows:

  • 64-bit memory array laser programmable
  • On-chip voltage limiter
  • Full-wave rectifier on chip
  • Large modulation depth due to a low impedance modulation device
  • Very small chip size convenient for implantation
  • On-chip 480PF resonance capacitor
  • On-chip supply buffer capacitor
  • Operating frequency 100-150kHz, typical frequency: 125kHz
  • Low power consumption

If you want to know the complete feature of TK4100, please download the TK4100 Data Sheet.


Due to the small volume of chip and antenna, TK4100 is easier to embed in a small and thin tag and key card. So the TK4100 Proximity ID Card could be a CR80 standard card or an irregular card, such as the key fob, animal tag, etc. It is widely used in the Attendance system, Access control system, Enterprise one-card, Membership Management, Car Parking System, logistics, Animal identification, security system, and other applications.
