The following user story has been written for a new application being developed to pre-book a space at a National Car Park.

As a vehicle driver

i want to be able to pre-book a car parking space online, selecting a disabled driver's space if needed

So that l can pay in advance and receive confirmation of my parking space number.

The following acceptance criteria have also been written:

•Payment can be made via PayPal, Debit or Credit Card

•Confirmation of payment and car parking details should be sent after the booking process is completed

•Driver information is stored in the reservation database

The database has been built and tested in a previous sprint, but the interface to the different payment methods have yet to be developed
