You need to pay to continue to use the software every year. If you don't upgrade, there will be letters across the whole item you scanned.. Never used a scanner where yearly payments were necessary. Don't recommend.

I don't use it very often, but when I do I realize I should use it a lot more often! I like to scan all my important travel documents, then email copies to myself and family back home in case I lose my originals while on the road. Super easy to use, even for low tech consumers such as myself.
