CyberCash - How it Happens
- 1.Consumer has shopped the merchant's site and decided what it
is they
wish to purchase, where they want it shipped,
etc.... Merchant server
returns a summary of the item, price,
transaction ID, etc. to consumer.
- 2.Consumer clicks on the "Pay" Button which
launches the CyberCash,
Checkfree or Compuserve Wallet and chooses
which credit card from
their "wallet" they wish to pay with and
clicks OK to forward the order
and encrypted payment information to the
merchant.
- 3.Merchant receives the packet, strips off the
order and forwards the
encrypted payment information digitally signed
and encrypted with his
private key to the CyberCash server. The
merchant cannot see the
consumer's credit card information.
- 4.CyberCash server receives the packet, takes
the transaction behind its
firewall and off the Internet, unwraps the
data, reformats the transaction
and forwards it to the merchant's bank over
dedicated lines.
- 5.The merchant's bank then forwards the
authorization request to the
issuing bank via the card associations or
directly to American Express or
Discover in those cases. The approval or
denial code then is sent back
to CyberCash.
- 6.CyberCash then returns the approval or denial
code to the merchant
who then passes it on to the consumer. From
Step 1 to Step 6 takes
approximately 15-20 seconds.
