I purchased the portable scanner to compile all my receipts. It worked fine for a while but quit when I reloaded when upgrading to windows7. The company says it changed or updated it’s software to make it work again but I would have to pay $30.00 to get it. It seems that every time they update software I will have to purchase it again. Nice thought for them but I will just scan and place in my own created folders. Their software does that for you and makes it retrievable with key words but how often do I need to do that. Microsoft updates for free along with all other manufactures that I know of. I think charging for updating is a scam!
