We are looking for an iPhone app, that can scan barcodes (1D) by the built-in camera.
When a barcode is scanned, the application must look in a local database for the barcode/e-ticket. If the barcode is present in the DB, some values have to be set in de DB. So it has to work as a e-ticket scanner.
There must be an option to import a database (external by HTTP) and also an option to export the database (also by HTTP).
Some example apps: Ticket HQ, QRickets 4, codeREADr
Contact me for any further information.
