The page shows a row of payment-card icons. It does not spell out which cards, wallets or processors the checkout accepts.
A card badge indicates card payments are expected. It does not name the payment processor, and we have not tested the checkout. If you prefer a particular card or a digital wallet, you will see at checkout whether it is offered.
A padlock in the browser shows the connection is encrypted. It does not show that the seller is trustworthy, so it is only one of several checks.
Confirm the domain, avoid public Wi-Fi for payments and use a credit card or a method that offers dispute protection. Be suspicious of requests for information a store does not need. Save a screenshot of the total and note the name that appears on your statement afterward.
