Build iOS app with barcode scanner and API connection

Job ID: 32608924

Budget: €250 – €750 EUR

We need an app that allows the user to do the following:
- The user needs to be able to create an account and login with this account.
- The user needs to be able to buy credits using the Apple AppStore payment system. These credits should be assigned to the account.
- The app should have a 2D barcode scanner that the user can use to scan a 13 digit product barcode.
- The user needs to be able to enter an API key in their account. This API key is used to make a connection, each user uses their own API key.
- After the user scanned a barcode, the system needs to check if it is a 13 digit code. If this is not the case, an error message will show. If the code is 13 digits, there will be an api request send. The API will send back some information that should be displayed to the user.
- The user can fill in fields to calculate a price
- After the user filled in the fields he has the option to submit it, when he submits the field there is a new api request send.

The app needs to be published in the iOS AppStore and needs to connect to a database (for user login and saving the API) the data in the database should be secure and encrypted for obvious reasons.
