The big boys on the net tell us that ecash is
necessary to invigorating the internet economy. There
are a couple of different schemes for using cash on the
net:
1. Digital Cash: Users have an electronic bank
account that is useable on the net. These bank
accounts generally require that you have an
additional piece of software that lets you use
the cash with your favorite web browser.
2. Net Checking: A play on digital cash. It
requires that you give a third party your checking
account number and all of your transactions
require that you fill out a digital check.
3. Credit Cards: Many of the larger credit card 
companies are developing the technology to let you
use your credit card to conduct business on the
internet much like you might do with a mailorder
catalogue over the phone.
