When entering the item number for a shop card transaction, which key typically needs to be pressed to confirm?

Pressing the Enter key to confirm an item number in a shop card transaction is a standard operation in many point-of-sale systems. The Enter key functions as a way to send input for processing, indicating that the user has finished entering the relevant information and is ready to move forward with the transaction. This action helps to streamline the process, allowing for quick execution of commands and maintaining the efficiency expected in a busy retail environment like Costco.

In a typical transaction flow, once the item number is entered, the press of the Enter key serves to validate that entry and initiate the next step, which could involve displaying item details, pricing, or further options about the transaction. Other keys mentioned, such as Confirm, Proceed, or Transaction, might not be standard across all systems or could be specific to different processes, which is why the Enter key is the right choice for confirming an item number.
