I am managing an inventory of 7,000 units of items in a company that is NOT in the US. I know that life could be easier. I want to be able to update the quantity on a handheld scanner each time I scan an item (Portable one).

For example I receive 50 items. I want to be able to scan only one of them and type 50 on the handheld.
I want to be able to download the data from the handheld to my computer where all the item codes and entered quantities from the scanner to go to their specific column.

Please refer me any Barcode Scanner that is able to do this with a budget of US$ 500. Please send me a link.

(Please do not recommend me a software. Just the hardware).

Thank you so much.
