The concept relates to the remaining monetary value available for use on a stored-value card specifically designated for purchasing pizza from a particular establishment. For example, if a pizza card was initially loaded with $50 and a customer uses $20 of that value to buy a pizza, the resulting prepaid card state would be described as having the monetary amount left.
Proper accounting of these values is vital for both the business and the consumer. For the business, accurate balance tracking allows for effective revenue management and customer loyalty program administration. For the consumer, awareness ensures they can effectively utilize the stored funds and avoid declined transactions. Historically, physical punch cards were used; the electronic equivalent offers increased security and tracking capabilities.
