Went to cebit computer expo in Sydney. Scanned the email I got from them on a machine. Worked perfectly.
Molly was lamenting that we should have paperless coupons where we simply show the coupon on a device. One national implementation of this has been in place for years. Traffic conditions in many cities are sent over FM transmission and can be received by GPS units to aid in navigation. My Garmin Nuvi receives these and will calculate the fastest route factoring in current freeway speeds. To support this service, ads are also sent out. Often these are discount coupons to local restaurants and hotels. These can not be printed out, these can only be shown on the device.
