I found a company in Italy who offer Micro Me, a personalised key fob with an NFC chip inside configured as a VCARD.
On the site you can create your own avatar and add you contact info and they produce it as a plastic key fob.
I was intrigued to know the protocol on the chip and how they could make a VCARD tag that would work on both Android and iPhone so I bought one and here’s the skinny: inside the fob is an NTAG 215 with only one record. This is a personalised URL to a page that dispenses your contact info. Users who scan your fob land there and get the choice to follow the links to a site, email, phone call etc or download all the data into their address book.
The fob and the landing page look great and work well but of course there are a couple of drawbacks: Your address book data is stored online so if you want to use the cute page delivery format you are locked into their system. They offer a service to change your VCARD data for a fee of €3.
Of course, you lot being you lot, you can simply reprogram the chip to do whatever you want.
