Description

The TK4100 is a low-frequency (125 kHz) read-only RFID chip based on CMOS technology. It boasts extremely low power consumption and is compatible with 125 kHz RFID systems. Each chip contains a pre-programmed unique identifier (UID). TK4100 cards are widely used in access control systems, hotel room cards, ID cards, SIM cards, membership cards, and public transportation cards. The TK4100 card uses the standard CR80 size (86 × 54 mm) and is available in various materials, including PVC, PET, PET-G, and PC, with thickness options of 0.8-0.9 mm or 1.8 mm. We offer blank cards compatible with most card printers and provide custom printing services, allowing you to personalize your cards with logos, text, or images without affecting RFID performance. As a direct replacement for EM4100, HT4168, and 4100D chips, this proximity card can be easily deployed without any modifications to your existing system.

Key Features

Operating Frequency: 125 kHz.

Manufacturing Process and Stability: CMOS process, low power consumption, durable, and stable long-term read/write operations.

Modulation and Encoding: Supports multiple data encoding formats, including Manchester, Bipolar, and PSK.

Read-Only UID: The chip comes with a unique, fixed identifier (UID) at the factory, facilitating authentication and system binding; it does not support user-side rewriting.

Read Reliability: Stable performance under common access control card readers/sensor modules, with good resistance to environmental interference.

FAQ

1. Can the UID of a TK4100 card be rewritten?
No. TK4100 is a Read-Only chip with a fixed factory-programmed UID that cannot be modified.

2. Is the TK4100 compatible with EM4100 systems?
Yes. TK4100 is designed to be compatible with EM-format systems and can be used as a direct replacement in most applications.

3. Does card printing affect RFID performance?
No. Printing on the card surface does not affect reading performance as long as proper materials and printing methods are used.

4. What is the typical read range?
Usually between 2 and 15 cm, depending on the reader’s antenna size, power, and environmental conditions.

5. Can it be used for encrypted or secure transactions?
No. TK4100 does not support cryptographic authentication. For secure applications, use MIFARE or Java Card solutions.
