This Blank RFID Card (PVC Card) operates at the exact frequency of 125kHz and features the T5577 chip. It offers Read/Write capabilities, making it ideal for cloning and writing IDs from standard 125kHz cards (like EM4100/TK4100). It works seamlessly with 125kHz RFID readers (e.g., the RDM6300 module) for Arduino and ESP32 projects. CRITICAL NOTE: Operating strictly at 125kHz, this card is NOT compatible with 13.56MHz readers, such as rc522 tags, or smartphone NFC modules.

 

Reliable 125kHz Identification & Access Control

Whether you are setting up an office access control system or sourcing reliable rfid cards cyprus for your local IoT projects, the 125kHz T5577 card delivers the flexibility you need. Unlike standard read-only rfid keyfobs, the T5577 chip allows for complete data writing and rewriting, making it the perfect solution for access card cloning applications. It stands out as an essential component among arduino components for Makers and Smart Home enthusiasts.

Key Features

  • Read/Write Operation: Fully rewritable design. Perfect for backing up or cloning standard EM4100 / TK4100 access cards.
  • 125kHz Operating Frequency: Utilizes the industry-standard low-frequency (LF) access control band.
  • T5577 Chip: Integrates a 330-bit EEPROM memory for storing identification IDs.
  • Durable Construction: Made of high-quality blank PVC, ready for thermal printing if required.

Frequently Asked Questions

Q: Is this compatible with the Arduino RC522 reader module?
A: No. The RC522 reader operates exclusively at 13.56MHz. This card functions at 125kHz, so you will need a corresponding low-frequency module, such as the RDM6300, to read or write it.

Q: Can I read/write this card with my mobile phone's NFC?
A: No. Smartphones only support NFC technology which operates at 13.56MHz. They do not have the internal antenna required to read older 125kHz LF standard tags.
