The scanner works great for various types of scanning. I have installed two of these scanners at a remote location and the users have have scanned ID cards, legal and letter size documents. The ID card scanning is a bit tricky to work out, but when done correctly, works great every time. I wish they would have included a slot to put the card in that fits it perfectly, but on an inexpensive scanner, you have to make your choices. If you only need a small desktop scanner that scans at about 25 to 30 pages per minute, you can't go wrong with the 3120.
