How to scan RFID tags in mendix application

Hi all,   There is requirement in my project to scan RFID tags using scanning device. I have below questions: Is there any specific widget available in marketplace to implement this. How can I connect external devices (in my case RFID tags scanning device) to my mendix application. Note: I am finding this solution for web application. Any help will be appreciated, Thanks in Advance.   Thanks, Rahul Patil

Hi Rahul,


The most scalable solution is an RFID reader that can scan and publish a message on MQTT. Mendix has in the Marketplace 3 MQTT modules. I’m using, but when using AWS MQTT broker, I would go for this:  I use the first one for AWS too.


You can build an app without additional logic (like MQTT) if you choose an RFID reader that emulates a keyboard in your app over a supported browser. The disadvantage is you need a computer with a browser for each RFID reader you need to implement. Of course, an Arduino or Raspberry can be used for this. This would also imply you need to be logged in. I would use the MQTT one to give access to a room, as the opener could also be triggered over an MQTT message. This will work if it is used for handheld scanning in a warehouse where RFID tags are driving by.


Handheld scanners with RFID and a browser should be considered in that case as a valid option too.


I would not advise using a JavaScript-integrated RFID as this would require staying logged in on the application, and it would be harder to make it resilient.
