What is the Campaign Date feature in QRCodeChimp, and why should I use it?

The Campaign Date feature lets you automatically control when your QR code is active. You can set a start and end date for your marketing campaign, and your QR code will only be active during that time. This is helpful for limited-time promotions, seasonal campaigns, product launches, or events. If someone scans the QR code outside the selected date range, they will still be able to scan it, but will see a message that the QR code is not active.
