13,56 MHz RFID Access Card, Slim, W26 bit Numbering

13.56 MHz RFID Access Card

are contactless radio frequency identification technology-based access cards that are often used in security systems, such as for opening doors, in transport systems, libraries or for check-in at workplaces. The term «China chip» may refer to lower-priced or universal RFID tags/chips that are manufactured in China and are widely used in various cost-effective solutions.

Product Description:

Frequency:
13.56 MHz (High Frequency – HF)

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

• UID changeable chip – rewritable UID

• MF1S50 compatible – 1K EEPROM, 16 sectors, 4 blocks per sector

Standard:

• ISO/IEC 14443 Type A

Material:
PVC plastic (white or print-ready)

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

Operating Range:
5–10 cm (depends on reader)

Features and Benefits:

• Passive card – requires no battery, operates on radio frequency field

• Cloneable – ability to change UID (requires special writer)

• Data Writing and Reading – 1KB EEPROM for data storage

• Compatibility with Many Readers – compatible with most MIFARE® Classic systems

• Printable Surface – suitable for printing logos, name and ID

• Pre-printed number in DEC or W26 format

Attention:

• If the chip has a changeable UID, it is not suitable for all MIFARE® systems that verify UID authenticity.

• Original MIFARE® Classic 1K chips do not allow UID modification – China chips (F08, UID changeable, etc.) are alternative solutions or for testing purposes.

• Not Compatible with 125 kHz readers – for 13.56 MHz devices only.
