My prototype app based on the MakeMeAPass website is up and running. You simply select the card type, use the camera to scan the barcode and hey-presto, you’ll have a passbook pass to add.
The usual issues still apply, such as some scanners being unable to scan barcodes on Passbook.
I’m planning to add simple location awareness too, once I get version 1.0 into the store. It will be available to download for 99p.
