13.56 MHz RFID access chip, with key ring, black.

Description

13.56 MHz RFID access chip, with key ring, black.

– are contactless radio-frequency identification (RFID) chips used for 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:
13,56 MHz (High Frequency – HF)

Chip:
China-manufactured clonable or compatible chip, typically:

• UID changeable chip – clonable and rewritable UID.
• MF1S50 compatible – 1K EEPROM, 16 sectors, 4 blocks per sector.

Standard:

• ISO/IEC 14443 Type A

Numbering:
engraved, sequential numbering.

Material:
PVC plastic

Color:
Black

Reading distance / operating range:
5 – 10 cm (depending on the reader)

Features and advantages:

• Passive card – does not require an internal power source (no battery).
• Clonable – UID change possible (requires a special writer).
• Data read/write – 1 KB EEPROM for data storage.
• Compatibility with many readers – suitable for most MIFARE® Classic systems.
• Printable surface – suitable for logos, names, and ID printing.
• Printed number in DEC or W26 format.

Attention:

• If the chip has a changeable UID, it may not be compatible with all MIFARE® systems that verify UID authenticity.
• Original MIFARE® Classic 1K chips do not allow UID changes – “China chips” (e.g. F08, UID changeable variants, etc.) are alternative solutions used for testing or non-standard implementations.
• Not compatible with 125 kHz readers – only for 13.56 MHz devices.
