i write this utility to help comics/books collectors to identify "on the road" missing items, the utility is totally free, and store the list of barcodes on a text files to help users to "print" the entire list.

Just scan barcodes of your collection , click "ADD" and after that the barcode number will be stored on SDCARD.

to remove an item (maybe when sold) just scan the barcode and press "REMOVE"

very very useful if you have 1000+ comics/books
