TOUCHMEMORY RW1990 Rewritable iButton Chip

The TOUCHMEMORY RW1990 is a high-quality rewritable iButton chip engineered for efficient use in modern access control systems. This electronic key provides a reliable solution for identification and security management, allowing users to perform multiple read and write cycles as needed. Constructed from durable metal with a galvanized finish, the device is built to withstand daily wear and tear while maintaining consistent performance across various environmental conditions.

Advantages

The primary benefit of the RW1990 iButton is its versatility in access control applications. Because it is rewritable, it offers significant flexibility for administrators who need to update or change access permissions frequently without replacing the physical hardware. Its robust metal construction ensures long-term durability, while the galvanized coating provides essential protection against corrosion, making it suitable for both indoor and outdoor installation environments.

Suitable for

• Intercom systems for residential and commercial buildings
• Access control for restricted areas
• Employee identification and time tracking systems
• Security management for gated communities

When it may not be suitable

This chip is not compatible with systems that require non-rewritable or read-only iButton keys. Furthermore, it may not function correctly with readers that do not support the specific communication protocol used by the RW1990 series.

Key specifications

• Material: Metal
• Finish: Galvanized
• Functionality: Rewritable
• Compatibility: Standard iButton readers

How to use

To use the RW1990, simply present the chip to the compatible iButton reader installed on your access point. If you need to program or rewrite the chip, use a dedicated iButton programmer device. Place the chip into the programmer's slot and follow the software instructions to write the required identification data onto the chip. Once programmed, the key is ready for immediate use in your access control system.

What to consider before purchase

• Verify that your existing access control hardware supports rewritable iButton technology.
• Ensure you have access to a compatible programming device if you intend to rewrite the chip data.
• Check the physical dimensions of your current reader to ensure the iButton form factor is compatible.

Usage recommendations

For optimal performance and longevity, keep the contact surface of the iButton clean and free of debris. Avoid exposing the chip to extreme magnetic fields or high-voltage electrical discharges, as these may interfere with the internal data storage.
