is being built, but the product is not yet

ready to be made available to the

general public.

_{The idea is to have a small wallet-sized PC that}

could be used to display messages, sc



_{It could also connect to the Internet and to}

the "Information Superhighway."



_{In addition, the wallet PC would eliminate the}

need for cash. Instead of using coins and paper

bills, money would be transferred using digital

cash stored in the Wallet PC.
