In many cases, in many units, some important documents, such as insurance policies, legal documents, and contracts, are very important in the management and use of these documents. Once lost, the consequences will be serious. When there are a lot of these files, it is very troublesome to find it once you want to use a certain file. Accordingly, our company uses RFID technology to develop a PDA document tracking management system to help users improve their ability to manage and use these important files.
1. Overview of the basic system
The full name of RFID is Radio Frequency IDentification, that is, radio frequency identification. This is a technology that can replace the existing traditional barcode. It transmits identification information in a non-contact and non-linear visible way to achieve the purpose of identification. It has more than 20 years of application history in animal tracking, anti-theft systems, access control management, parking lot management, automatic production lines, and material management. An RFID tag is actually a tag with a chip and an antenna. It uses electromagnetic waves to transmit specific identification information in a non-contact, non-visual, and highly reliable manner.
This system is realized by using the above characteristics of RFID tags. In order to search and search documents faster, in order to track some important documents in the work, it will be attached (pasted) in each document. An RFID tag containing a unique code and related information. The PDA is used to read and write the content on these tags. Because the PDA has a built-in database, the types, date of establishment, validity period, confidentiality level, related personnel, main content and tracking codes of these documents can be entered into the database together. With the passage of time, the database can also effectively record the borrowing, reading personnel and usage of each file.
As mentioned above, the PDA has a built-in database and can effectively read and write RFID. Therefore, it has the following main functions and features:
1. Create new document information on the PDA, and can edit, modify and delete documents;
2. There are many ways to quickly search the required documents and materials in the database;
3. Use the PDA to read the RFID chip pasted on the document to quickly search and search for the document, and you can search and search for multiple documents at the same time; avoid searching one by one and improve efficiency;
4. Establish and view the borrowing, reading personnel and usage status of the files on the PDA.
5. The system can be easily expanded and upgraded.
6. Since the entire system is built on PDA, it is small in size, light in weight, easy to carry, and convenient to use; at the same time, it has a cost advantage.

Two, expand the system
For units with many documents, especially those with highly confidential documents, you can use the expansion system of this system, install an antenna door on the entrance and exit door, and the data in the database on the PDA and the database on the computer Data synchronization, which can effectively prevent documents from being stolen, and at the same time it is more convenient for effective management of documents.
