RFID Reader Software for Windows

posted in: PC Applications | 0

This is an application I created in Visual BASIC 2005 Express which allows a Parallax RFID Reader Module (#28140 or #28340) connected to a PC to read and display tag data.

This application has a small form which allows you to select and open the COM Port for the RFID Reader Module and enable or disable reading as necessary. By default the RFID Reader Module is enabled when the COM Port is opened. Optionally you can trigger a System Beep during each read. The RFID Reader Module is disabled for 1.5 seconds after a read. This delay is provided to avoid duplicate reads. The RFID Reader Module is then re-enabled. Once tags are read into the text box they can be copied into a database or other application, speeding tag entry.

 

This shows what the application looks like when it is first run. Your COM Port values may vary.

 

This shows what the screen looks like after a COM Port has been opened.

 

This is after reading 4 tags from the RFID Reader Module Sampler Kit. Your tag numbers will be different.

 

Known Issues

  • The software currently only checks registered COM ports on startup. So if you add a port after the application is running it will not appear in the list. This could be fixed by refreshing the port list during some other event, such as closing a port.
  • If you click the Close Port button during a read the application will lock up. This could be solved by disabling the Close Port button during the read cycle.

 

Visual BASIC Express

For those that are interested in modifying or enhancing the application, Visual BASIC Express can be downloaded free from the Microsoft website at http://www.microsoft.com/express/vb/

 

Downloads

There are two files available for download. The first ZIP file is the VB Express 2005 setup package for installing the RFID Software onto your PC. This usually requires you to have all updates of the .NET framework installed on your PC.

The second ZIP file is the VB Express 2005 Source Code. This is basically the project folder zipped up. So you would place it in your projects folder, usually in a VB folder within your documents folder. Using this project/source with newer versions of Visual BASIC may require you to upgrade the project, which should be done for you. Please leave a comment below with any questions, suggestions or feedback.
