"Experience designers love a bit of Saarinen: “Always design a thing by considering it in its next larger context – a chair in a room, a room in a house, a house in an environment, an environment in a city plan.” That’s what’s wrong here, an RFID card is not considered within the context of a wallet, containing multiple competing RF field creating information and ID objects, and this new, electric wallet isn’t considered within the larger system of shops and the invisible RF world." Companies don't design for seams - and, as Chris points out, when they do, it's for seams between all their own products.

"People are understandably jittery, after the numerous social networking data breach debacles of three years ago that seemingly turned a generation off of oversharing. MTC have gone to great pains to assure users of the system that their data is safe from "getting zucked", and they've begun to provide free personal monitoring services to users of Clipper." Mike writes future-history, and in the midst of it, coins a lovely neologism.

Anne on New Zealand's Snapper card, and getting used to the rhythm of its RFID reader. I found the fact that the government will sell you a USB reader - so you can top up at home - fascinating.

"Having produced these visualisations, I now find myself mapping imaginary shapes to the radio enabled objects around me. I see the yellow Oyster readers with plumes of LED fluoro-green fungal blossoms hanging over them – and my Oyster card jumping between them, like a digital bee cross-pollenating with data as I travel the city." More wonderful stuff - both in terms of imagery and writing - from the BERG/Touch collaboration.

"The film Nearness explores interacting without touching. With RFID it’s proximity that matters, and actual contact isn’t necessary. Much of Timo’s work in the Touch project addresses the fictions and speculations in the technology. Here we play with the problems of invisibility and the magic of being close." God, I work with brilliant people.

"...as the cards become more prevalent, and the features of one card start to trump another people end up carrying multiple cards with overlapping functions. The only way for the user to know which card to use? Gosh - to remove the card from the wallet. Convenience indeed."
