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.
