It is possible to run API calls using a QR code and that is the direction I have been working to implement. For instance this code generates a QR code using the "Create Child Record" button that quickbase creates automatically when it sets up a relationship:
"<img src=https://chart.googleapis.com/chart?chs=200x200&cht=qr&chl="&URLEncode([Add Selection])&">"
The code for that [Add Selection] is the API_GenAddRecordForm that the button uses. The way I have it set up is I have a pieces table, a pallet table, and a join table that allows me to relate the parts to the pallets. The QR scan creates a record in the join table associated to the pallet and opens it in edit mode so that a piece can be scanned and the record can be saved.
The problem with this approach is that it requires the user to scan the pallet code, select the "part #" field, scan a part code, save the record, and then repeat this process for every part that the user want to put on a pallet. Ideally I image that a user would scan a pallet, scan all of the pieces that they want on that pallet, and then select a save button.
