When Chaumian money comes into wide use, I think that for most end users we will have to stash all unused tokens inside smartcards. However, because of the critical mass problem, initial deployment for small payments cannot rely on such means, though initial deployment for large payments could.
Here in Hong Kong, contactless "Octopus" smartcards (based on the Sony FeliCa device) are well established for paying fares on buses, ferries and subways, and also for small transactions with vending machines, convenience stores and supermarkets. The implementation is definitely non-Chaumian (it's based on symmetric encryption using shared secrets for both mutual authentication and secure transfer of value) but the cards can be purchased and reloaded with cash. Alas, the system does not allow uploads of value to banks or peer-to-peer transfers, as Mondex did. For those who may be interested, the standard is ISO/IEC 14443: http://makeashorterlink.com/?O1B042DE1 The card's specs are at: http://www.sony.net/Products/felica/pdf/833e.pdf Reader: http://www.sony.net/Products/felica/pdf/441e.pdf General info: http://www.sony.net/Products/felica/index.html Second source: http://www.mitsubishi.co.jp/iccard/main/3_smart/smart.html Enzo ----- End forwarded message -----
