Problematics surrounding credit cards
1) The idea of the credit card is to make it easier to spend money, to encourage consumption. 2) An early problem was to become international, which involved removing "America" from the company name, and switching to the name, Visa. The rise of credit card use corresponds to a rise in international monetary flows. 3) In the history of credit cards, the speed of payment is always an issue (Cite Restaurant revolt of 1959). 4) The problem of identification is always an issue.
How does the credit card imprinter address each of these issues? What does it make possible and what are its limitations?
Money Form Plate Press —Perfect reproduction —Non-verbal
Paper —Multiple Inscription —Duplicate —Signature Filing system
Skeuomorph—The information of the card is materially arbitrary, but semiotically necessary
Semiotic stuff to preserve transparnecy
The credit card imprinter does not care if you have a real or fake
The authetication is not built into the transaction before the swipe—which is to say that the press would work when the swipe now doesn’t
A contract if deferring the problem of authentic
Functional nonsense—All bullshit design, specials spirals, etc… Aside from the serial number and amount—just hard to copy.
Encoding—human and machine readable (only one part of the inscription, though)
Signature as self-identify—the obvious
Formal prohibitions—Generic authenticating and accounting mechanism
