<p>A payment card system for use in remote transactions wherein a cardholder may create additional accounts subsidiary to a principal payment card, each such account having its own unique payment card number compliant with existing standards and protocols and each credited in advance by transfer from the principal account with a specified amount available either to meet modest or mini payments below a specified level and otherwise only to meet the cost of purchases from specified merchants, whilst disabling the principal payment card from being used in remote transactions, such that a variable payment card account number is used for each transaction, the principal payment card numbers are not at any time at risk, merchants may be certain of payment without possibility of repudiation of the transaction without needing to identify the cardholder, and thereby enabling remote anonymous transactions to take place both in the real world and in a virtual world.</p> |
