Generic RW1990 Reproducible Rewritable TM Card - 8KB Inductive RFID

The RW1990 card operates on the 125kHz Low Frequency (LF) RFID band. It uses inductive, contactless technology, requiring a compatible 125kHz RFID reader for communication. The card is passive, meaning it draws power from the reader's electromagnetic field during operation.

This card features 8KB of EEPROM memory, which is rewritable. This capacity allows for storing substantial data such as unique identification numbers, access permissions, user details, or log entries. The memory supports multiple read and write cycles, enabling data updates throughout the card's lifespan.

The integrated 64-bit security pin provides a basic layer of protection for the data stored on the card. It helps prevent unauthorized reading or cloning of the card's contents, making it suitable for secure applications like access control where preventing token duplication is important.

The RW1990 is designed for robust performance with an operating temperature range of -40°C to 85°C. This wide range allows for reliable use in both extreme cold and hot environments, making it suitable for outdoor applications, industrial settings, or vehicles.

Yes, the 'Reproducible' designation means multiple cards can be programmed with identical data, useful for issuing cards to multiple users in a system. However, the 64-bit security pin and unique factory-programmed identifiers provide safeguards against unauthorized reproduction or cloning for malicious purposes.
