Machine-implemented two-part bank-card-backed financial transactions

A cash-dispensing machine comprising:

• a controller that controls automated operations of the cash-dispensing machine;
• a card reader that receives and reads a bank card;
• one or more cash cassettes that store paper currency;
• a cash dispenser that dispenses paper currency from the one or more cash cassettes per instructions from the controller;
• a user-interface device that renders information to a user of the machine and receives and forwards instructions from the user to the controller;
• and
• a network interface that enables the controller to communicate with one or more other nodes, wherein the cash-dispensing machine enables the user to perform a two-part bank-card-backed financial transaction comprising (i) purchase of a negotiable instrument via a quasi-cash transaction and (ii) redemption of the negotiable instrument by:
• (a) the card reader receiving and reading a bank card inserted by the user and transmitting corresponding retrieved banking information to the controller;
• (b) the user-interface device receiving a request from the user for a current two-part bank-card-backed financial transaction and transmitting the request to the controller;
• (c) the controller using the network interface to communicate with the one or more other nodes to purchase a current negotiable instrument via a current quasi-cash transaction;
• (d) the controller enabling the user to redeem the current negotiable instrument;
• and
• (e) the cash dispenser accessing the one or more cash cassettes to dispense, to the user, paper currency corresponding to the redeemed current negotiable instrument.
