A cover picture for the explainer in Topic.md: a contactless card tapping a payment terminal, with a soft trail of deep blue light running off toward a distant bank building on the horizon, a clean editorial illustration on a plain light background, calm white and one deep blue accent, no text. Reference (Topic.md): # Topic - **Question:** How does a card payment travel from the tap to the bank? - **For:** Engineers new to payments. They know how software systems and APIs work, but nothing about cards, banks or how money moves between them. - **They should understand:** A tap is only a fast yes or no. The money moves later, in a separate batch, through the same chain of parties. - **The parts:** Card, terminal, acquirer (the shop's bank), card network, issuing bank (the cardholder's bank). Explain each with an everyday analogy and no protocol names: the card is a key, the terminal a messenger, the acquirer the shop's bank, the card network a postal sorting hub, the issuing bank the keeper of the cardholder's money. - **The steps:** 1. The customer taps the card on the terminal. 2. The terminal reads the card and sends a request to the acquirer. 3. The acquirer passes it to the card network. 4. The network routes it to the issuing bank. 5. The issuing bank checks funds and risk, then answers yes or no. 6. The answer travels back through the network and acquirer to the terminal, which shows approved or declined. 7. Later, in a batch, the money is settled from the issuing bank to the shop's account. - **Compare:** Authorization vs settlement. Authorization is the instant approval that holds the amount and happens in seconds. Settlement is the batch that actually moves the money, usually a day or more later. Rows: when it happens, what it does, who is involved, what the shop sees. - **Numbers:** Under 2 seconds for an approval. About 2% in fees on a typical sale. 1 to 2 days for the money to arrive. 5 parties between the tap and the bank. - **Look:** Light and editorial: a calm white page with one deep blue accent, like a good technical magazine. One typeface family, generous space. - **Sources:** None. Draw only on the notes above.
