David Pogue has found a useful tool for his workflow and his recent column, A Better Way to Manage Receipts for Business Travel, is all about how he makes use of the NeatReceipts scanner and NeatWorks software.
I have no experience with that particular scanner but the NeatWorks software looks tempting. I have the ScanSnap S300M, which is a wonderful scanner with duplexing capabilities. It too can handle the small receipts up to legal sized paper. I was pleasantly surprised to see the NeatWorks is listed as compatible with my scanner.
So, if you have a scanner already, check it against their list to see if the software is compatible before sinking the cash into another scanner just to get the capabilities demonstrated by their software.
