13.56 MHz + 125 kHz dual-frequency RFID access card.

Description

13.56 MHz + 125 kHz dual-frequency RFID access card.

Frequencies:

• 13.56 MHz (HF – high frequency, e.g. MIFARE® Classic, ISO14443A).

• 125 kHz (LF – low frequency, e.g. EM4100, TK4100, HID clones).

Key fobs:

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

  • 13,56 MHz: MIFARE® Classic 1K kloon, UID changeable chip

  • 125 kHz: EM4100, TK4100, T5577 (clonable and reprogrammable).

Material: PVC plastic (white or printable).

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

Reading distance / operating range:

• 125 kHz: up to 10 cm

• 13,56 MHz: up to 5–10 cm (depending on the reader)

Features and advantages:

• Dual frequency – operates in both LF and HF systems.

• Universal compatibility – can be used with both older 125 kHz and newer 13.56 MHz readers.

• Clonable – especially useful for testing, cloning, and development purposes.

• Battery-free – passive card powered by radio frequency energy.

• Printable – suitable for printing logos, QR codes, or personal data.
