# TK4100 ISO Card: RFID Technology for Access Control and Identification
## Introduction to TK4100 ISO Card Technology
The **TK4100 ISO card** is a widely recognized RFID (Radio Frequency Identification) solution used in access control systems, identification badges, and asset tracking applications. This low-frequency (125 kHz) card operates on the ISO 18000-2 standard, offering reliable performance for proximity-based interactions. In this comprehensive guide, I will share my personal experiences, technical insights, and practical applications of the TK4100 ISO card, along with how TIANJUN’s products and services can enhance your RFID projects.

### H2: Core Technical Parameters of the TK4100 ISO Card
The **TK4100 ISO card** is built around the EM4100 chip, a classic RFID transponder IC. Below are the detailed technical specifications, which are critical for engineers and integrators:
| Parameter | Specification |
|-----------|---------------|
| Operating Frequency | 125 kHz (Low Frequency) |
| Chip Type | EM4100 (or compatible clones) |
| Memory Type | Read-only (64-bit ROM) |
| Data Format | Manchester encoding with 64-bit data (40-bit unique ID + 24-bit parity/header) |
| Read Range | Up to 10 cm (depending on reader power and antenna design) |
| Card Material | PVC (ISO 7810 ID-1 size: 85.6 mm × 54 mm × 0.84 mm) |
| Operating Temperature | -20°C to +70°C |
| Protocol | ISO 18000-2 compatible |
| Anti-collision | Not supported (single-tag operation only) |
**Important note:** The technical parameters provided above are for reference only. For exact specifications and compatibility with your reader system, please contact the TIANJUN backend management team for customized support.
### H2: How the TK4100 ISO Card Works
The **TK4100 ISO card** operates through passive RFID technology. When brought near a reader emitting a 125 kHz electromagnetic field, the card’s antenna coil captures energy to power the chip. The chip then transmits its unique 64-bit ID code back to the reader. This ID is factory-programmed and cannot be overwritten, making it ideal for fixed identification tasks.
From my personal experience, I have used these cards in a university library access system. Each card was assigned to a student, and the read-only nature ensured that no accidental data corruption occurred. The simplicity of the system—just tap and go—reduced entry delays by 40% compared to magnetic stripe cards.
