What type of use could you get out of this at home? really curious.....have you had a use for it? if have'n one has got some kind of cool advantage then count me in !
I think that it is for reading and editing barcodes and also for keeping track of receipts ( you could scan receipts and then throw them away and it will store your receipts on your computer)
It is stated on the specs of the item that it comes with a 12ft RS232 Serial E/P Cable and a power supply; do you have those items as well or only what it is on the picture?
