Business cards are a fact of life. But filing them and being able to find the right card quickly is a major hassle. For the last few weeks I've been scoping out a business card scanner but the cost is, in my view, prohibitively high given that it's a piece of hardware that I'm only likely to use a few times a year.

Most scanners come with some software that performs optical character recognition, or OCR, on cards and then uses the text to populate a new entry in your address book. CardSnap turns your iPhone into a business card scanner. Rather than loading all the OCR onto the iPhone, CardSnap lets you photograph a business card. Once you've checked that the image is OK you send the card up to an online service where the OCR is performed. A couple of hours later, the scanned card comes back and you review the result of the OCR.

I put CardSnap through its paces by scanning a pile of 80 cards. Each card was photographed with my iPhone 3GS. It's worth noting that this app relies on the 3GS's superior camera. If you've only got a first generation iPhone or a 3G then you'll need to shell out for Griffin's Clarifi iPhone case as CardSnap relies on a decent camera to get the best result from the OCR.

Once a card is photographed it goes into a queue that you can view using the "Cards" button. From submission to return it takes about 24 hours although we received some cards within a couple of hours.

The OCR process was quite accurate although we did encounter some problems. For example, where the business card didn't have a country on the address the software populated the field with United States. I'd prefer to have an option to set the default country. Also, when an address had a dash or slash in it, like 2-4 Smith Road, the dash or slash was omitted.

Once a card comes back from OCR processing, it's important to review the card. As the photo of the card is retained this is reasonably easy although having a way to review the card and see the photo at the same time would make that much easier.

As well as testing CardSnap with a batch of cards we've used it at meetings to quickly capture the cards of other people. It works well - there's lots of "cool" factor when you do this - although it does mean that my meeting trick of arranging cards in front of me on the table so I don;t forget names is not longer practical as I don't keep the cards any more.

At $9.99USD ($12.99AUD) CardSnap is much cheaper and more portable than a business card scanner. It works quite well and the OCR accuracy is over 90%. The daly between scanning and receiving the result is annoying but given that I'd probably not carry a scanner to every meeting it doesn't make the actual workflow any slower.

If you collect lots of business cards and lack the time or discipline to enter all the details into your contact list then CardSnap is excellent value.
