The Bell System developed a Transaction Telephone intended to speed such credit card verification inquiries. I don't think they ever were widely used; a plain Touch Tone set could do the job almost as easily, without the extra cost of a fancy phone. Since the inquiry is a very brief transaction, a low bandwidth continuous line would've worked out well, however, I don't think that approach was taken too far. articles on this: http://www.telephonecollectors.info/index.php/browse/catalogs-manuals-educational-docs-by-company/western-electric-bell-system/publications-and-educational-documents-by-date/blr/11685-74dec-blr-p358-credit-authorization-transaction-telephone/file http://www.telephonecollectors.info/index.php/browse/catalogs-manuals-educational-docs-by-company/western-electric-bell-system/publications-and-educational-documents-by-date/blr/11706-75oct-blr-p377-transaction-telephone/file http://www.telephonecollectors.info/index.php/browse/bsp-bell-system-practices-by-doc/dfmp-dial-facilities-management-practices/604-dfmp-f-10a-i1/file
