"Pinless" refers to a technology or method that eliminates the need for a physical pin or code for authentication or access. This approach is often used in various applications, such as mobile payments and secure logins, where users can verify their identity without entering a traditional PIN. Instead, alternatives like biometrics or one-time codes may be employed. In the context of payment systems, "pinless" transactions can enhance user convenience and speed. For example, with digital wallets, users can make purchases quickly without the hassle of remembering and entering a PIN, making the process more efficient and user-friendly.
