Hello all

I am making a project which is based on shopping malls.

its very simple one to understand , the basic idea of project is that :-

i want to build a microcontroller based Reader which have numeical keypad and a LED (or LCD) on it and it would be given to customer when he enters mall , then which ever products he wants he will pick it and enter its item code in the reader ( item code is printed on item) , and then press enter in reader and then enter the item quantity , , he will repeat the process for the number of products he wants and then will go to Counter , and give his reader to the receptionist and then receptionist will connect his reader to the computer (may be through Hyper terminal software) and then take the print of that and give to customer.


so the requirement in this project is the Microcontroller based READER which has numerical keypad along with a Enter key and a display screen ,, which is capable of recieving inputs and store it and a RS232 port so it can be connetced to PC

Can anyone help how can i make this reader ??,, what would be the components required ?? and what would be approximate cost.....
Pls help Its urgent..............
