Credit cards of the type found in the United Kingdom and United States are unusual in France and the closest equivalent is the deferred debit card, which operates like a normal debit card, except that all purchase transactions are postponed until the end of the month, thereby giving the customer between 1 and 31 days of "interest-free" credit.

Schlumberger developed the first telephone chip cards for France Telecom and the Swedish telecommunications operator Telia in the early 1980s. The company developed ties with telecommunications operators in several countries, and played a role in industry-wide efforts to develop new digital mobile communication standards, particularly the GSM transmission standard (Global System for Mobile Communication).

This chip can be charged with up to 200 euro, and is advertised as a means of making medium to very small payments, even down to several euros or cent payments. The key factor here is that no processing fees are deducted by banks. It did not gain the popularity its inventors had hoped for. As of 2020, several partners pulled out of accepting the Geldkarte which is no longer issued and set to be retired altogether in the near future.

The magnetic stripe card was invented in 1960 by IBM engineer Forrest Parry, who conceived the idea of incorporating a piece of magnetic tape in order to store secured information and data to a plastic card base.
