===Costs of payment===
An analysis by the [[Deutsche Bundesbank]] in 2017 found that a cash payment in retail costs an average of 24 [[euro]] cents, while payments with a [[girocard]] cost 30 cents (or often 0.3 to 0.4% of sales plus a transaction fee) and with a [[credit card]] charge one euro which is included in the sales price.<ref>{{Cite book |title=Der Weg des Geldes: Grundlagen, Entwicklungen und Perspektiven des Bargeldes in Deutschland. |last=Beermann |first=Johannes |publisher=Siedler |year=2022 |isbn=978-3-8275-0165-3 |pages=179–206 |language=de |series=20 Jahre Euro.

Depending on the account model, there are also booking costs for the account holder with an average of 35 euro cents charged for each(!) account posting. Because of this convenient source of income, commercial banks and credit card companies favor cashless payments.

In the case of cashless payment transactions, in addition to the documentation of the payment itself, the personal details of the payer are usually linked to the data of the payee according to the [[Know Your Customer]] (KYC) principle. This enables the payment process to be precisely traced for the payer and the payee. The constant increase in digitization leads to a more detailed recording of cashless payment transactions and their evaluation for advertising and marketing campaigns. Since this digital documentation is usually more centralized than before, the potential for abuse increases. On the other hand, the cash transactions are anonymous, unless purchasing profiles are recorded with the help of [[loyalty program]]s based on customer cards, and keep the payment landscape competitive.<ref>{{Cite web |date=2022-02-09 |title=Why Cash Matters |url=https://www.cashmatters.org/why-cash-matters-top-20-reasons-for-the-popularity-and-relevance-of-cash |access-date=2022-12-12}}</ref>
