The front-end system provides a "gift mode" function, allowing operators to mark products entered in specific modes as gift products. The system automatically sets the amount of gift products to 0 and does not include them in the receivable amount.

Gift operation process:

1. Enable gift mode

Click on the "Other" - "Start Giving" button in the POS front-end interface, and the system will enter gift mode. The interface should have a clear visual prompt (such as the input product displaying a "gift in progress" status indicator)

2. Input of gifted goods

In gift mode, the input goods will be automatically marked as "gift" attributes, and the system should automatically set the amount of gift goods to 0, or mark them as "gifts" and not include them in the receivable amount.

3. End the gift mode

This gift function supports two ending methods: ① Automatic Ending - After the current document is issued, it will automatically revert to normal sales mode. ② Manual End - Use the "Other" - "End Gift" button to actively exit the gift mode.
