TK4100 is a CMOS integrated circuit for use in 125KHz read only RFID cards. It is compatible with EM format and is is a type of low-frequency (LF) RFID chip commonly used in proximity cards.
What format is TK4100 card?
Here is an analysis:
- Frequency: This card operates at 125 kHz, a common frequency for basic RFID applications.
- Read-Only: The TK4100 chip is typically read-only, meaning the data stored on it cannot be modified after manufacturing.
- Simple: It is a relatively simple and inexpensive chip, making it suitable for basic access control and identification needs.
- Compatibility: It is compatible with most 125 kHz RFID readers.
Key Applications:
- Access Control: Basic access control for buildings, offices, and events.
- Time and Attendance: Tracking employee attendance and work hours.
- Asset Tracking: Basic asset tracking within a limited range.
Due to its simplicity, the TK4100 chip has limited security features. For applications requiring higher security, more advanced technologies like MIFARE or DESFire are recommended.
What is an RFID card used for?
RFID cards are used for applications where tracking or identifying personnel is important or where access control is required. Various RFID frequency bands are utilized in cards today, including 125 kHz low frequency proximity, 13.56 MHz high frequency smart card and 860-960 MHz ultra-high frequency (UHF).
