Something I've been considering is a easy and simple way to share business contact information. In comes EnBizCard with a super easy solution to host your contact information in a responsive HTML format.
You can generate the zip file directly from there site and then paste into your site or other hosting service. Once you have that you can setup a NFC card or QR code to direct people over to your digital business card.
There's no need to print new cards every time you update a phone number or other information, simply update the files and you are GTG (good to go).
I found some clear NFC cards to try out, and setting the NFC tag to go to the URL of my contact card works great.
