Swatch Access for Dreamcast
From Sega Retro
Swatch Access for Dreamcast was a planned peripheral for the Sega Dreamcast that interfaced with Swatch Access watches. Swatch Access is a series of watches with one of two types of data chips inside them: a SkiData chip, which allows for access to various ski resorts, or a chip that allowed for payment of all sorts of things, including drinks, public transport, museum passes and tickets.
By using "Internet & Wearable" technology, the Swatch Access watch would have interfaced with the Dreamcast via a controller plugin (shown right) using the RFID technology inside the watch. A Swatch Access connected Dreamcast could immediately read the data incorporated in it and access to the indicated Internet site by only shading Swatch Access. Swatch Access could read the data from various kinds of sites on Dreamcast via Internet and write the data into the watch.
