Description

EM Proximity Access Card (ISO Standard)

• Type: Read-only, NOT writable
• Frequency: 125 KHz with encrypted access
• Factory Programmed: Unique, tamper-proof 64-bit code

Key Features:

• Power-Efficient: Operates without a battery, powered by a built-in coil that draws energy from a matching reader’s magnetic field.
• Reliable Transmission: Continuously sends 64 bits of data stored in an EPROM array whenever within the reader’s range.
• Secure Data Modulation: Utilizes Manchester Coding for data output, with a bit rate synchronized to 64 periods of the field frequency.
• Optimized Functionality: Achieves precise performance through a capacitor adjusted in parallel with an external coil for optimal resonance.

Compatibility:

Designed for use with the GK4001 reader, specifically for Read-only, NOT writable cards
