Descripción

Key Technical Features:

• Operating Frequency: 125kHz, a low-frequency RFID technology suitable for contactless, short-range identification.

• Storage Capacity: 330 bits to 363 bits, divided into 10 or 11 data partitions, supporting user-defined data writing.

• Security Mechanism: Supports 8-bit password protection and multi-level encryption authorization, ensuring high data storage security and strong tamper resistance.

• Durability: Over 100,000 write/erase cycles, data retention up to 10 years, with anti-magnetic, anti-static, and anti-vandalism properties.

• Packaging: Can be made into standard PVC cards or irregularly shaped cards (such as keychains, wristbands, etc.) for diverse applications.

• Read/Write Distance: Typically 3–10cm, achieving contactless data transmission via radio waves.

Although the T5577 is often mistakenly referred to as an “IC card,” technically it belongs to the category of low-frequency RFID cards, rather than true smart IC cards (such as MIFARE or CPU cards) with a CPU and operating system. However, due to its programmability and emulation capabilities, it can be “written” to simulate other card numbers using specialized equipment, giving it a unique advantage in access control duplication and system debugging.
