Description

The RW1990 is an inductive RFID token operating at the standard 125 kHz frequency. It utilizes electromagnetic coupling for contactless data transfer, enabling secure identification and authentication without direct physical contact with the reader. The integrated 8KB EEPROM memory supports multiple read/write cycles, allowing for dynamic data updates and reprogramming throughout the token’s lifecycle.

Designed for industrial and commercial environments, the token features a robust operating temperature range from -40°C to +85°C, ensuring reliable performance in both freezing and high-temperature conditions. Its 64-bit unique identifier (UID) provides a foundation for secure access control systems, while the rewritable memory allows for flexible application in asset tracking, process control, and personnel identification.

Key Features

  • High-capacity 8KB rewritable EEPROM for flexible data storage
  • Inductive 125 kHz RFID technology for reliable, contactless operation
  • 64-bit unique serial number (UID) with security pin protection
  • Extended operational range from -40°C to +85°C
  • Compact and durable token design for integration into cards or key fobs
  • Supports standard RFID reader/writer protocols for broad compatibility
  • Optimized performance-to-cost ratio for volume deployments

Frequently Asked Questions

What frequency does the RW1990 RFID card operate at?

The RW1990 operates at the standard 125 kHz inductive frequency. It is compatible with the majority of common 125 kHz RFID reader/writer modules used in access control and identification systems.

Can data be written and rewritten to the RW1990 card?

Yes. The card features 8KB of rewritable EEPROM memory, allowing data to be updated, modified, or completely reprogrammed multiple times throughout its operational life using a compatible 125 kHz RFID writer.

What is the 64-bit pin protection used for?

The 64-bit value provides a unique identifier (UID) for each card and can be used in conjunction with a security pin to protect memory blocks from unauthorized read or write operations, enhancing system security.

What is the typical read range for this token?

As a passive, inductive RFID token, the read range is typically a few centimeters, depending on the power and antenna design of the reader. Optimal performance is achieved when the token is placed within the reader's electromagnetic field.
