  • MOTO transactions require credit rating systems, e.g. as run by large catelogue companies New channels are outside the existing model, so invent SSL, SET etc (see Next slide) If new devices accept IC cards, then new functions required by online merchant servers Managing new transport protocols, databearers, error handling, encryption etc required Standard interface provided into the existing transaction payment schemes More fundamentally, the inefficiencies of subscription as a method of payment, especially in the mobile telephony and Pay-per-view TV industries, indicate enormous opportunities. Conservative studies estimate 20% of the cost of a mobile telephone call is related to billing and bad debt; new figures from Equifax, the marketing and information service provider, show that 9.4% of UK mobile phone bills went unpaid during the third quarter of 1997.

  • - the scenario begins by the mobile user contacting the `coke server` in the network, e.g. by typing in an address printed on the vending machine. - this sceanrio is for a weak POS which is not connected to the network; the solution when the POS is connected is the same as the regular web solution. - the POS needs only very minimal processing, to verify the `receipt` which is an authenticated message from the `coke server` in the network. Notice this is simple, efficient shared - key authentication - very inexpensive. - some communication mechanism is required to send the receipt - it could even be manual (i.e. the mobile displays a code to be manually entered into a small keypad on the vending machine). Or of course IR / Bluetooth / anything else can be used.
