Android barcode scanner

Brief description: We need android application that scans barcode/qrcode from camera, decodes it, sends the decoded string to the server and shows server response to the user. This project includes only android application, no server-side programming. We think that the easiest way will be to customize an existing application. ==================== Detailed description: 1. Core functionality: Step 1: Take barcode from the camera. Step 2: Decode the string encoded in barcode. Step 3: Send the decoded string to the server. Step 4: Receive response from the server. Step 5: Show the response to the user. 2. Most likely, we will need to establish some security measures to make sure that the data is sent to the server only by authorized users. For this at Step 3 we will additionally send the hash of the decoded string and user's password (or maybe username/password combination). Password (or username/password) must be entered by the user once upon application installation (no need to enter it each time). If the user changes his password on our site, he should be able to change it in android application as well. Possibly, the password will be validated by the server when entered. Possibly, the application will request to re-enter password if server sends "Invalid hash" response. 3. If it is not difficult, the response from the server may be html page (instead of plain text). 4. We may need to re-brand the application. 5. We may need the application to decode qrcodes in addition to barcodes. 6. We may need help to publish this application in app store. 7. In the future we may need iPhone application with exactly the same functionality. 8. If it is not difficult, we may need testing version that we can use from desktop. 9. If it is not difficult, we may need server-side solution that generates barcodes. ==================== Please, give a separate quote and time estimate for each part. If you porovide total bid, write which parts are included into it. Please, do not include parts 7-9 into total bid. Optimally, we need at least part 1 to be made on this week (i.e. by 26 Aug). We think that the optimal solution will be to customize an existing application, for example [login to view URL] Zxing includes both android and iPhone applications. If you have some other application that you can customize, please, suggest and preferably send .apk file that we can test.
