What are the benefits of UHF RFID technology used in building permit application tracking?

Depending on the type of permit, the application may need to be reviewed for 10 different items within the DSD. Also, there are several reviewers for each review project. This is very challenging to track the actual location of each permit application in real time.
In the construction service department of Florida in the United States, which is part of the Sustainable Development Department (DSD), it applies RFID technology to track building permits, realizes real-time monitoring of the circulation of official documents, saves time and improves customer service levels.
In any given month, DSD has issued more than 2,000 building permits, and more than 6,000 permits need to be reviewed. In addition, there are usually two licenses for large-scale DSD programs, and the approval process for these licenses is not a straight line. The licenses usually need to be returned for additional review or revision, and the same review project may need to go back and forth. several times.
| Project plan:
By deploying the RFID solution, ThingMagic-RFID reader reads the label information on the license, can see how the license is reviewed, and determine the specific real-time location.
At each review item point, install 1 to 3 8 dBi circularly polarized antennas, and then connect to ThingMagic’s Vega UHF industrial-grade RFID reader. Vega integrates an M5E UHF RFID module, which can read tags within a maximum range of 9 meters. The three reverse TNC antenna ports support a single station 5050 ohm antenna. Each device is connected to the middleware SPT (developed specifically for the project) running on the PC via USB. The computer uses the existing Ethernet connection to transfer data to the cloud.

The 8dBi UHF circularly polarized external panel antenna RFA915-8R90 has the characteristics of high gain and low standing wave; it can be conveniently used in UHF RFID frequency bands such as access control, storage, logistics, and retail.

At the same time, the project uses Avery Dennison’s UHF tags, and each tag prints a unique identification pre-code.
RFID radio frequency tag
Each RFID label is printed and pre-coded with an identification number. Starting from the establishment of the printout of the building permit application, the RFID label starts to be marked on the document. Then use the RFID reader to read the information printed on the RFID tag and connect to the PC via USB. This process links files and tag IDs and imports them into the cloud-based software IntelliView SPT, which includes middleware to manage these data for tag reading and inventory management applications.
When the tag file passes through the RFID reader, the online data is updated in real time. Authorized users can use any browser at any time, use any device to connect to the Internet to access this information.
| Project Benefits
The use of RFID technology to track construction permit applications has improved work efficiency. Because many of the staff’s working time is devoted to the work itself, rather than searching for files. For the staff, knowing the real-time location of the application is the most important.
