Sleutelhanger-tag Promag GiTAG1Q-20K 125 kHz RFID-sleutelhanger

Promag GiTAG1Q-20K is a 125 kHz RFID key chain tag (keyfob) designed for access control and identification systems. This passive keyfob stores a single ID that is transmitted at low frequency (125 kHz) when read by compatible proximity readers. Its tear-drop form and compact key chain design make it suitable for everyday carrying on key rings in commercial and residential environments, and it is available in a dark gray finish.

Advantages

The GiTAG1Q-20K provides a simple, passive identification solution that requires no internal power source and operates reliably with readers supporting 125 kHz tags. Its programmable ID enables integration into existing access control and time attendance systems. The key chain form factor offers convenient attachment to keys or lanyards and a durable casing suitable for frequent handling.

Suitable for

• Door entry and access control systems using 125 kHz proximity readers
• Time and attendance tracking where low-frequency RFID tags are supported
• Asset tagging for low-cost identification of equipment and small items
• Proximity-based authentication for residential or light commercial use

When it may not be suitable

This keyfob operates at 125 kHz and requires a compatible reader; it will not function with readers that support only higher-frequency standards (such as 13.56 MHz) or passive UHF systems. It is intended to store and transmit a single ID and is not designed for high-capacity data storage or complex multi-application use cases.

Key specifications

• Technology: Passive low-frequency RFID
• Operating frequency: 125 kHz
• Form factor: Tear-drop key chain tag (keyfob)
• Color/finish: Dark gray
• Programmability: Stores a programmable ID for access/identification

How to use

Attach the Promag GiTAG1Q-20K to a key ring or lanyard and present it to a compatible 125 kHz reader within the reader's operating range. The reader will detect the tag's stored ID and process it according to the connected access control, time attendance, or inventory system. For initial setup or replacement, ensure the tag's programmed ID is registered in the target system according to the system manufacturer’s procedures.

What to consider before purchase

• Confirm that your readers and access control systems support 125 kHz passive RFID tags.
• Verify that a single-ID, low-frequency keyfob meets your security and data requirements.
• Consider the physical size and color if you require specific keyfob visibility or branding.

Recommendations

Use the keyfob for everyday proximity authentication by holding it briefly near compatible readers; avoid exposing it to strong magnetic fields or prolonged immersion in water to preserve performance and casing integrity.
