Now you can virtually hand your business card to anyone. Take one minute and create your paperless business card at twtBizCard.com. Then add the #twtbizcard hash tag to the person you’re Tweeting with, and your card info will be sent automatically.

For a mobile phone specific app, check out DUB. It will work with nearly all brands of cell phones. DUB also connects with LinkedIn. Plus you can send your paperless card via SMS. Just text “DUBME” and your recipient’s email address or mobile number to 32075.

There’s a third way to go paperless that uses two dimensional bar codes called “Quick Response” or “QR” codes. The guys from AdWaveUSA.com were by our offices the other day giving us a demonstration.  It’s pretty cool. Using QR codes for paperless business cards is just one application for this scanning technology. You can include a QR code on your cell phone, in a print ad, even on a t-shirt. The recipient just needs to download a simple scanning app to their cell phone, and when they scan your QR code, it will deliver any information you want: From business cards, to print ads, to websites.

iPhone offers the Optiscan scanner and generator app for $4.99.
