Follow up to API usage for trade show badge scanning thread in January

[API usage for trade show badge scanning] This was the thread that I was reading

So I was searching the community support to see if there is a way to have an Intuiface application that can scan a QR code that users would have to reveal a list of prizes they can choose from. The QR codes are physically handed out and they would hold them up the “screen/camera” that would then scan the code. I read that you need a third party scanner (the Zebra DS457 was the one that was recommended) and I am hoping to get more information regarding this type of application and what is needed to connect the Zebra scanner to the screen that is running the Intuiface application.

Thank you for any help!
