Digital Cash: A Probable Future by Michael E. Marotta mercury@well.sf.ca.us Kinkos Copy Centers have instituted a debit-card. You put your federal reserve notes in a machine and increment the electronic card. Then you use the card in their public copiers. The card is anonymous. I have two because Kinko's doesn't warranty the cards: I don't carry more than $5 on a card. I have yet to trade the card anywhere else for goods or services. This is the sine qua non of money: money is any medium of indirect exchange. So far, you can only use the Kards to buy Kopies. Digital cash will not replace other forms. Federal Reserve paper passes on the street, perhaps, but gold and silver coins are still being made anew by the USA, PRC, other governments, and several private mints. Plastic, checks, and fiat banknotes have not removed the need for gold nd silver. If anything, government money reinforces the need for real cash: "Aurem non olet" means "Gold doesn't smell" i.e., cash leaves no traces. Digital cash could come from banks via ATMs. You increment your DigiKash card from your demand account or from FRNs in your wallet. You goto a store, pick what you want. You pass through the Exit. You wand or scan your goods. This clears their security. You insert your DigiKash card. It is debited. You package your goods (or put them in your cloth shopping bag) and you leave the store. There was a time when the Grocery Store had clerks. You gave one your shopping list or told them what you wanted and they got it for you. Then came the "supermarket." Self-serve. What a concept. This paradigm shift occured about 1945. We will see another. The retail clerk is on the way out. MacDonald's already ordered 75 robots. Debit cards remove the cost of employees. You'll use your DigiKard for fastfood. You'll use it at the gas pump. (They already take credit cards.) The assumption today is that you will use your BANK debit card for all of this. I'm not sure. I think that the first bank that offers anonymous debit cards will make a fortune. How? Well, for one thing, here in Michigan, Kinko's takes 4% off top for sales tax. Also, I'm walking around with unspent money on my card while Kinko's has my money earning a return. ATMs already cost me 75 cents per transaction. Make it an even buck and it will work for debit cards. Debit cards would be sure winners at Computer Rental stores. The MSU library has a bank of gopher terminals and Gov. Engler just separated property taxes from public education. Gophers seem like a fungible to me. The library already sells pens and copying is a cash business for them now. Public transit is another obvious choice -- the famous Orange card of Japan. Commuter trains in Chicago that toddlin' town had them in place in 1977. But debit cards don't _promise_ universality. You can't use your Kinkos Kard on the train -- yet. ------------------------------------------------------------------------------ ( ) "Money rests on the axiom that every man is the owner of his mind.
