Frequently Asked Questions

No. Traditional 1D laser scanners only read linear barcodes. Scanning 2D QR codes on paper or smartphone screens requires a 2D optical area imager scanner. Check the final destination, mobile layout, and printed placement before distributing the code to users.

Use dynamic single-use tokenized URLs that invalidate after first checkout, enforce customer account login rules, set minimum purchase thresholds, and embed clear expiration dates in POS logic. Use a destination you control and review it periodically so long-lived printed material does not lead to an error.

Construct a direct store URL that includes the discount parameter (such as /discount/CODE on Shopify), append UTM tracking tags, and encode the complete string into a static QR code. Provide a visible alternative when the workflow depends on a particular camera feature, app, account, or network connection.

Matte or uncoated stock is usually easier to scan because it limits reflections, but glossy displays can work when lighting and viewing angles are controlled. Keep strong contrast and a complete quiet zone, then test the final printed and mounted display under the store's actual lighting before production.
