Task: To develop a web component that generates a QRCode (two-dimensional bar code) and an Android component that recognizes the codes on devices and passes information using soap calls to the server

Solution: Developed an Android application that reads QR Code, decrypts the information and passes it to the web service in real-time using a basic ASP.NET test page. The test page requests data and generates a QR Code, in which the information is encrypted. The Android application reads the QR Code, decrypts and validates the information, then uploads it to the web. The Android application has a password protected setup option for administrators that allows them to configure the phone for specific QR code scanning. The app includes statistics showing the activity of QR Code uploaded to the web and the total of QR Codes scanned by terminals and other details.

Task:
Develop a routine for Android that uses ksoap2 library to perform soap calls to a specified server and the returned reply object array as actionable dynamic buttons.

Solution:
On startup the application performs a web service call with the user’s phone number to check the account information and obtains the list of categories available for the account. Categories are presented for the user as actionable buttons within a scrollable screen. The user can choose the category; open the screen to enter a description and dollar amount for a new transaction and submit the data to a web service.
