Éénklik

Éénklik (one-click) is a term used in Dutch to describe a digital interaction that completes a task with a single click or tap. The most common instance is one-click checkout, where a user can place an order immediately, using previously stored payment and shipping information. The concept can also apply to other single-action workflows, such as software installation, account sign-in, or submitting forms.

Originating in the context of online commerce in the late 1990s, éénklik was popularized by platforms offering a stored profile to reduce checkout steps. In a typical implementation, a token or reference links the user’s account to a device, browser, or session, allowing the action to execute without re-entering details. Security and privacy controls, such as authentication, tokens, and the option to revoke stored data, are important components.

Advantages include faster transactions, higher conversion rates, and a streamlined user experience. Drawbacks include the risk of unintended purchases if a device is accessible to others, potential privacy concerns, and dependence on the security of saved data. Many systems provide safeguards such as confirmation prompts, authentication requirements for new devices, or the ability to disable one-click functionality.

From a design perspective, éénklik emphasizes clarity and accessibility. Interfaces should ensure that the single-action control is clearly labeled, keyboard-navigable, and compatible with assistive technologies. Regulatory and consumer-protection considerations emphasize consent for storing payment details and transparent terms of use.
