Business card reader, where to start
If you plan to use your document scanner mainly for filing text or less sensitive graphic documents, you can make do with a document scanner that has a resolution of 600 dpi or less. This resolution should be sufficient for most basic uses. In some cases, you will need a document scanner with a much higher resolution. For extensive photo scanning work along with your regular document filing, you may want to consider buying a flatbed scanner. There is a wide array of different models on the market, many with advanced features and attachments.
