(I’m a big fan of dotted or dashed lines, it’s a great visual trick for representing hidden things. Glad to see that Mike is taking up this language, we should develop it further!)

Here’s the description of the talk in full, the slides are available from slideshare and at Mike’s weblog:

Things have long had identifying marks, from silversmiths’ hallmarks to barcodes, but mating machine-readable identification with pervasive networking greatly increases the value of the marks.

For example, when a machine-readable identification method such as an RFID or a high-density visual code is combined with the wireless networking of a mobile phone, a new way of interacting with everyday objects is created. Once you have the capability uniquely identify anything immediately, you can attach meta information to it. Any meta-information. How much is this worth on eBay? Which of my friends has one? Will this go with my Mom’s china? Will it make me sick if I eat it? Was it made by children?

I call this digital representation as accessed through a unique ID, an object’s “information shadow” and I now see them attached to just about everything. Beyond getting meta information, however, lies an even more powerful concept: changing the physical object to a service, for which the thing you’re looking at is but a single instantiation of that agreement. It’s already happened to media, and to car-shared cars and shared bicycles in urban areas.

When this happens, the objects have to change at a fundamental level. They have to be designed differently and they have to be described and discussed differently. The “owner’s” relationship to the object changes. The very idea of ownership changes. The solid object grows a dotted line that is filled-in as-needed, when-needed, and with the features that are needed. This is not the same thing as renting or co-ownership, its anytime/anywhere nature-enabled by the underlying technology makes these new service objects fundamentally new.

Many recent products point in this direction, where objects such as the Amazon Kindle are useless without the service contract, where a Nabaztag/tag is an empty shell waiting for connection to a network full of personal information and social connections, and where NFC phones and RFID peripherals are just the touchpoints between the online and the offline.

The ikTag is an extremely simple interface for social networks, both on and offline. Mediamatic developed the ikTag for people to do nice stuff with their online profile without sitting behind your computer. The ikTag is an innovative and cultural application of RFID technology.

Also, in the past few days, O’Reilly has launched an RFID system at Etech:

That’s why we are giving all of the attendees at ETech RFID tags that can be linked to their conference profiles. Activating your RFID tag and linking it to your profile will be completely opt-in, but with these tags you can interact with several projects we’ll have at the conference.

As we discovered with the Picnic photo booth, there are lots of interesting opportunities to be discovered when a physical tag is linked to a social network…
