Laptop scanner, an in-depth review
Not only that, but if you have a lot of contacts you can scan their business cards and keep them together. Probably the main benefit you will get from using a portable scanner is the fact that it will prevent human errors in copying. Once you scan the document in you know you have a correct copy. You can find a good portable scanner for about $150. If it costs much more than that it will have a lot more features to use.
