The Doorking 1508-199 is a UHF license plate tag that allows for long-range vehicle identification and access control. It is a passive tag, meaning it doesn't have a battery and is powered by the reader's radio signal. When a vehicle with the tag attached approaches the reader, the tag transmits its unique ID number to the reader, which then grants access if authorized.

Here are some of the key features of the Doorking 1508-199:

1. Long-range reading: The tag can be read from up to 30 feet away, making it ideal for use with gates and parking lot entrances.
2. Durable: The tag is made of weatherproof material and is resistant to damage from dirt, dust, and moisture.
3. Easy to install: The tag can be easily mounted to a license plate using the included adhesive pad.
4. Affordable: The Doorking 1508-199 is a cost-effective way to improve security and convenience for your property.
