My little blog on scan receipts
Your portable scanner will also retain a digital copy of each receipt, if needed in the future. You can also take a portable scanner to a business meeting to scan and bring important documents back to the office for review. Scanners digitally file the documents and allow you to name them for retrieval by keyword search. You might be interested to know that portable scanners can also be used to capture and preserve your important personal documents like passports, birth and marriage certificates in the event of loss by fire. Replacing those documents will be so much easier if you have copies.
