Frequently Asked Questions

What is the operating frequency and read range of the RW1990 RFID card?

The RW1990 card operates on the 125 kHz Low Frequency (LF) inductive RFID standard. Typical read range is up to 10 cm (4 inches), depending on the power and antenna size of the compatible reader. It requires a corresponding 125 kHz RFID reader/writer for communication.

How do I write data to the 8KB memory on the RW1990 card?

Data is written to the card's EEPROM memory using a compatible 125 kHz RFID reader/writer module and associated software (e.g., connected to an Arduino, Raspberry Pi, or PC). You must provide the correct 64-bit security pin to authorize read/write operations. The memory can be segmented and rewritten multiple times.

Can this card be copied or cloned?

While the card's data can be read and rewritten with the proper security credentials, the integrated 64-bit security pin provides a basic level of protection against unauthorized cloning. For high-security applications, additional encryption protocols should be implemented at the system level beyond the card's native features.

Is the RW1990 compatible with HID or MIFARE reader systems?

No, the RW1990 operates at 125 kHz (LF), which is a different frequency and protocol than the 13.56 MHz High-Frequency (HF) systems like HID iCLASS or NXP Semiconductors MIFARE. You must use a reader specifically designed for 125 kHz inductive RFID cards.
