13,56 MHz RFID access fob, with ring, black

13.56 MHz RFID access key fob

- these are contactless access fobs based on radio-frequency identification technology, commonly used in security systems, e.g. for door entry, as well as in transport systems, libraries and workplace check-in. The term “China chip” may refer to lower-cost or universal RFID tags/chips manufactured in China and widely used in a variety of budget solutions.

Product Description:

Frequency:
13.56 MHz (High Frequency – HF) Chip:
Chinese-made cloneable or compatible chip, typically:

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

Standard:

PVC plastic Colour:
Black Read range:
5–10 cm (depending on the reader)

Features and benefits:

• Passive card – no battery required, powered by the reader's RF field
• Cloneable – UID can be changed (special writer required)
• Data read/write – 1KB EEPROM for data storage
• Compatible with many readers – works with most MIFARE® Classic systems
• Printable surface – suitable for printing logos, names and IDs
• Printed number in DEC or W26 format

Please note:

• If the chip has a changeable UID, it will not work with all MIFARE® systems that verify UID authenticity.
• Genuine MIFARE® Classic 1K chips do not allow the UID to be changed – China chips (F08, UID changeable, etc.) are intended as alternative solutions or for testing.
• Not compatible with 125 kHz readers – for 13.56 MHz devices only.
