Hints for successful barcode scanning:
* Make sure your device has auto-focus camera (iPhone 3GS/4/4S and iPad 3rd generation or newer are supported; iPhone 3, iPad 1/2 and iPod Touch are not supported);
* Ensure there is plenty of light;
* The distance between camera and coupon should be about 3 to 5 inches;
* Shake to force the camera to focus;
* Wait for the autofocus to finish;
* Hold still while scanning barcode.
The scanned "Expiration Date" is decoded from coupon barcode itself, sometime it is different from the printed "Expiration Date".
The scanned detail is decoded from coupon barcode itself, sometime it is different from the printed coupon description.
For example:
Scan Result can be "Get $1.00 Off when you buy item A or item B",
however the printed description is "Save $1.00 on any XXXXX product".
