Research: existing patents

Some further researcher into electronic business cards, I have found the following websites:

Electronic BC Exchange
http://www.freepatentsonline.com/6533171.html

Personal Data Interchange - vCard
http://www.imc.org/pdi/vcardwhite.html

Electronic BC Device
http://www.patentstorm.us/patents/6254001.html

"A method of transferring business card information from a first user to a second user includes the steps of providing said first and second users with an electronic business card device, storing data similar to that stored on a business card in a memory in each of the electronic business cards, selectively displaying at least some of the stored business card data on a visual display screen, and selectively transferring the stored business card data of at least the first user to the electronic business card of the other user for storage and selective retrieval."

I am not a member of the website so I couldn't view the full blueprint of the design, however by the look of it, it doesn't appeal to me as some high-class gadget - let alone appealing to my Gen X clientele. So this is where I come in!
