Grandstream GDS37XX NFC Tag G-AD2 MIFARE DESFire 13.56MHz AES-128

The Grandstream GDS37XX NFC Tag G-AD2 is a high-security contactless credential designed for seamless integration with Grandstream GDS3700 series door systems. Utilizing advanced MIFARE DESFire EV3 technology, this tag operates at a frequency of 13.56 MHz and provides robust protection through AES-128 encryption. As a passive device, it draws power directly from the NFC reader, ensuring reliable and maintenance-free operation for secure access control and facility management.

Advantages

This NFC tag offers a significant security upgrade over standard proximity cards by incorporating the AES-128 encryption algorithm, which effectively prevents unauthorized cloning and data interception. Its durable construction, featuring a combination of PVC and ABS materials, ensures longevity even in demanding professional environments. With a high read cycle capacity exceeding 100,000 uses and a wide operating temperature range, it provides consistent performance for daily authentication tasks in both indoor and outdoor settings.

Suitable for

• Secure access control for office buildings
• Restricted area entry management
• Integration with Grandstream GDS3700 series door stations
• Employee identification systems

This tag may not be suitable for systems that do not support the MIFARE DESFire EV3 standard or the 13.56 MHz frequency. It is specifically designed for use with compatible Grandstream hardware and will not function with legacy 125 kHz proximity readers or non-NFC enabled access control systems.

Key specifications

• Technology: MIFARE DESFire EV3
• Frequency: 13.56 MHz
• Encryption: AES-128
• Memory: 2 KB
• Operating distance: Greater than 10 mm
• Durability: Over 100,000 read cycles
• Operating temperature: -30 °C to 60 °C
• Dimensions: 41 mm x 32 mm x 3.8 mm

To use the tag, simply present it within the 10 mm range of the compatible Grandstream GDS3700 series reader. The passive internal circuitry will automatically receive radio energy from the reader to initiate the authentication process. No batteries or external power sources are required for the tag to function.

What to consider before purchase

• Verify compatibility with your existing GDS3700 series door station
• Ensure the reader supports MIFARE DESFire EV3 technology
• Consider the number of users requiring access credentials

For optimal performance, ensure the tag is not placed directly against metal surfaces, as this may interfere with the radio frequency communication between the tag and the reader.
