help with QR codes

Hello fine people,
Jared writing with a help request. I'm at a site where I may be able to fulfill orders to have delivered to different places. To refill some of the items, the boxes have QR codes. I tried using Cam Find which actually works well with bar codes, but the QR code yielded data metrics code, another scan yielded the color of the box, and yet another scan really didn't provide anything. Camfind says it is a QR reader, so what am I doing wrong? If I need another app, what should I be using? Thanks for any help.
