Which of the following is a common point of sale document?

A gift voucher or card is a common point of sale document primarily used in retail environments. It serves as a form of payment that can be used by customers when making purchases at a store. Gift cards are often issued by retailers and can be loaded with a specific amount of money, making them a popular choice for both gifting and personal use.

In the context of point-of-sale transactions, the gift voucher or card functions as an important document because it is presented at checkout to complete a transaction. This document is essential for enabling a seamless purchasing process and can often include details such as the card number, balance, and terms of use.

The other options, while relevant in retail, do not serve the same purpose in point-of-sale transactions. An employee handbook is meant for internal guidance for staff, an inventory log is used for tracking stock levels rather than for direct customer transactions, and a customer feedback form is utilized after a purchase to gather insights about customer satisfaction but is not part of the purchasing process itself.
