While we are discussing digital cash systems, I just happened to notice that a local BBS I use is now accepting a form of digital cash for subscriptions and services. They have solved the conversion problem between physical money and digital money in a rather interesting way which I thought I would pass along. Through a commercial firm by the name of True Media, Inc, located in Florida, one can obtain a 7 digit token in return for a $10 charge to ones phone bill by calling a 900 number. An automated voice system reads you the 7 digit number without the need for human intervention. Said tokens may then be enclosed in Email to the Sysop when requesting subscription upgrades and will be accepted as if they were real money. Although this is primitive compared to the protocols we have been discussing, it is kind of neat. Using an automated response system on a 900 number in order to convert dollars into digital tokens is an innovative approach. -- Mike Duvos $ PGP 2.3a Public Key available $ mpd@netcom.com $ via Finger. $
