125 kHz RFID access card (EM-Marine), thin.

Description

125 kHz RFID access card (EM-Marine), thin.

125 kHz RFID cards are contactless radio-frequency identification cards commonly used in access control systems, such as door entry, transportation systems, libraries, or workplace attendance tracking.
The term “China chip” may refer to lower-cost or universal RFID tags/chips manufactured in China, which are widely used in various budget-friendly solutions.

Product Description:

Frequency:
125 kHz (LF – Low Frequency)

Chip:
China chip – typically clonable or universal chips, for example:

• TK5200 – reprogrammable clone chip (TK4100 compatible).

Material:
Material: PVC plastic (white, printable).

Dimensions: 85.5 × 54 mm (standard ID card size, ISO/IEC 7810).

Reading distance / operating range:

Up to 10 cm (depending on the reader)

Features and advantages:

• Passive card – does not require an internal power source (no battery).

• Clonable (with T5577) – can be programmed in different formats.

• Read by chip ID – uses UID (Unique ID) only for identification.

• Durable and water-resistant – suitable for everyday use.

• Universal compatibility – works with many 125 kHz readers.

• Low-cost and widely used in mass production.

• Printed DEC number and Wiegand 26-bit number.

Typical applications:

• Door access control systems.

• Time and attendance systems.

• Apartment building intercom systems.

• Parking systems.

• Animal and asset identification.

Notes:

• TK4100 and EM4100 are read-only – the UID is programmed at the factory and cannot be changed.

• T5577 allows the card to be reprogrammed multiple times, making it useful for cloning and system testing.
