A Post Office wants to improve its efficiency by delivering lost letters and lost items (which are sent in packages) in a short period of time. It currently takes about 3 months to get a lost card or lost item to get to the correct destination. A machine reads addresses in letters. Those that could not be read by the machine, are ordered by human intervention. Even after this, the address is not readable, it becomes a lost letter. Items that fall out of the packet become lost items. When the sender / receiver calls or contacts the post office for your letter / article, a manual note is made and then this note is sent to the store where lost items and lost letters are stored. The reconciliation process of finding the lost card / item is manual and sometimes a wrong letter or item is sent. You have to develop a system, which captures the above functionality and reduce response time from 3 months to 10 business days.
In the existing system the manual method is used where initially each letter is verified by machine to find out the direction specified in the letter and the transfer but little machine can not understand some letters due to bad writing these letters are transferred to the manual department where each letter It is checked manually but in this case there are also few letters that are kept aside. In this case, after a few days, when the user requests the mailing department, it will take months to return what is the time the process takes. To solve this problem we developed a software application that can provide solution in 10 days.
The users have a front graphical user interface through which the user can update different information related to receiving postcards and lost postcards. Users can update the details of the lost card, the status of the complaint, the lost font ... etc. All these details are updated to the database for later use. Initially applications need to connect to the application with unique username and password that can be modified from the administration panel provided to the user.
