A two-part payment token is used during a transaction whereby a buyer
obtains goods/services from a seller. The token, which does not identify
the buyer, is given to a trusted third party (TTP) by the buyer. The TTP
releases a first part of the token to the seller who then releases the
goods/services to the buyer. Upon confirming receipt of the
goods/services by the buyer, the TTP releases the second part of the
payment token to the seller, who may then present both parts of the token
to the buyer's bank to obtain payment.
