13,56 MHz + 125kHz dual-system RFID access card

Dual-Frequency RFID Access Card – 13.56 MHz + 125 kHz

Frequencies:

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

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

Chips:

• China chip – typically cloneable or universal chips, e.g.:

  • 13.56 MHz: MIFARE® Classic 1K clone, UID changeable chip

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

Material:
PVC plastic (white or print-ready)

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

Read range:

• 125 kHz: up to 10 cm

• 13.56 MHz: up to 5–10 cm (depending on the reader)

Features and benefits:

• Dual frequency – works with both LF and HF systems

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

• Cloneable – especially useful for testing, cloning and development

• Battery-free – passive card, powered by RF energy
