This app allows you to scan Tesco Clubcards and Nectar cards and add them to Passbook.
You can choose up to ten locations where you want your pass to appear on the lock screen.
These passes will not work with Apple Watch, since these are 1D barcodes, which aren't supported. Apple have added some 1D barcode support to iOS 9, so I'll look at that in a future release.
Make Me A Pass is not affiliated in any way with any of the card providers. Your milage may vary as some optical scanners cannot always read barcodes when displayed on glass screens.
If you need any help or have any questions, please ask!
