Method of and system for electronic funds transfer via facsimile machines.

摘要

Account customized transaction vouchers, containing thereon a series of pseudo random alphanumeric characters with a different set of characters on each voucher, are completed by at least one party (20) to a transaction. The party transmits by facsimile (30) an image of the completed voucher to a facsimile machine (34) at a central facility (36). A character reader (35) at the central facility reads the incoming data and authorizes the requested transaction after comparison of the pseudo random alphanumeric set of characters on the voucher with a list in the account record of that party. Used sets of alphanumeric characters are deleted from the list in the account data to permit onetime usage of a voucher. A credit voucher is sent from the central facility to a facsimile machine (32) at the site of the other party (26) to the transaction. This voucher includes also a pseudo random alphanumeric set of characters selected from a second list in the central facility.
