Hi arangore87!!

Thanks for using NI Discussion Forums!!  I would strongly recommend that you keep a specific question on the same post, so we can all be on the same page on this and help you out in the best possible way.

Is there any toolbox for RFID in labview?

First, you have to define how you want to communicate with your RFID reader (via USB, TCP/IP, etc.).  Depending on this, you can use NI-VISA or call the DLL files from your device driver.

Hope to hear from you soon, so I can help you out with any available resources we have!

Regards!

Hi arangore87!!

It is not going to be an easy task to write a program to communicate with your device. Since there does not appear to be a driver set written for LabVIEW for this device by the manufacturer, you will need to get the communication protocol information and command set from the manufacturer. You will then need to configure NI-VISA to control your device. The following links will help you get started:
