If you want to do the business networking thing right, you'd better know who you met and when. Thank heavens keeping those pesky contacts straight is getting easier with a new generation of smartphone business card reader apps that turn your Apple (AAPL) - Get Report iPhone, Google (GOOG) - Get Report Android device, Microsoft (MSFT) - Get Report WinMo mobile phone or even your Symbian OS-based phone into an on-the-go, paperless business contact management tool.

Smartphone business card readers are apps that can read and understand images, phone numbers, addresses and other info off business cards via photos taken by powerful cameras on the new generation of

Droids, T-Mobile myTouch 4Gs or

HTC EVOs. Instead of taking a contact's cards, stacking 'em up and transcribing them later -- if you are especially diligent -- you snap a picture of the card, feed it into the scanning app and confirm the information is correct. Then hand that card right back to your new business buddy.

Not surprisingly, business card readers have become hot apps on the iTunes App Store, Android Market and Windows Marketplace. But selecting the right one isn't easy. Here are my picks for the latest and greatest in scanner apps:

CamCard Business Card Reader

for iPhone, Android and WinMo ($6.99)

IntSig Information

For data recognition, cross-platform support and all-around business use, it is tough to beat


CamCard Business Card Reader. For $7, your smartphone becomes an all-in-one business card scanning solution. Load the app, take the picture, scan the info and you're done. I was impressed with the quality of data capture, although high-concept, heavily designed cards will probably be a challenge to capture properly. And like with all readers, be sure to confirm that the info you scanned was captured correctly. The downside? If the camera on your smartphone takes a long time to be ready to take a picture, or is clumsy to use, expect an awkward moment or two with your new business contacts as you stand around taking pictures. It can get kind of silly.

DYMO CardScan Mobile

for Blackberry, iPhone and WinMo ($9.99)

Newell Rubbermaid

Yes, the

Newell Rubbermaid

(NWL) - Get Report

kitchen products company is in the app business, and it really does charge 30% more for about the same features and performance as the card scanner competition. But the fact is, DYMO's freestanding CardScan desk card scanner is the de facto standard in the business world. Look around and you will see them everywhere. And going with its dedicated app for your mobile phone makes the most out of these devices. Scanning quality is perfectly good, though I give the nod for quality to the CamCard. I will keep it simple: If you have DYMO CardScanner on your desk, get the CardScan Mobile app.

ABBYY Business Card Reader

for Symbian and iPhone ($4 at iTunes; Symbian version is $25 unlimited)


Symbian OS users, including all you
