RW1990 Reproducible Rewritable TM Card - 8KB Inductive RFID Token

The RW1990 card features 8KB of non-volatile EEPROM memory, which is fully rewritable. This allows the stored identification data or other information to be updated, erased, and rewritten multiple times throughout the card's lifecycle, supporting dynamic applications like changing access permissions or logging variable data.

The integrated 64-bit security pin acts as a password or cryptographic key that must be presented to the reader for any write or clone operation. This system prevents unauthorized devices from altering the card's memory or creating duplicate copies, ensuring that only authenticated systems can reproduce or update the token's data, which is critical for secure access control.

'Inductive touch type' indicates the card uses contactless RFID technology based on inductive coupling. It requires a compatible RFID reader that generates a magnetic field. To read or write data, you simply bring the card within the reader's activation field (typically a few centimeters). No physical contact or insertion is needed, which makes the system fast, reliable, and resistant to wear.

The RW1990 card is rated for operation from -40°C to 85°C. This wide temperature range makes it suitable for both indoor and outdoor applications, including harsh industrial environments, parking garages, or logistics yards where extreme cold or heat may be encountered. The card's construction is designed to maintain data integrity across this full spectrum.
