The Shopmium app is compatible with most phones in wide use:
- iPhone 5 and after (iOS 11.1 minimum)
- Android: version 5.0 and after (auto-focus mandatory on your device), except for small screens (ldpi or low resolution). The number of pixels must be 470dp x 320dp or higher.

The smartphone must have auto-focus. This is a feature on all iPhones, however, some Android phones do not have it. The auto-focus is required to claim cashback since it is used to scan the product barcode.

If you have a device with a camera that does not have auto-focus (i.e. iPod, iPad), you can visit to type in your UPC and generate a barcode in a bigger format to scan.
