Unfortunately not, at this time. Until Shopify grants developers access to the scan data from the Bluetooth scanner, we're limited to the built-in mobile device's camera.
Regarding inventory adjustment, I'm actively working on this and hope to have it ready in the next 1-2 months. I'll update this thread when the feature is live.
Hi @nicmondo, the stock adjustment feature for our app is now live (in beta). Due to decimal limitations we have to round each adjustment, but we capture the decimal remainder and take it into account for each adjustment, so over time it should be pretty accurate. I welcome you to give it a try, thanks!
@El_Atico the app is live in the app store with 14-day free trial: https://apps.shopify.com/scan-price-embedded-barcodes. However, until Shopify grants developers access to the Bluetooth handheld scanner, you will need to use the mobile device's built-in camera - I welcome you to give it a try.
