Why do I have / need a QR code?
When you’re ready to ask for recognition, pull up your QR code on your device and show it to your customer so he / she can scan it. The customer will be taken to a web page on their own device where they can leave feedback.
Other ways to show customers your QR code:
Take a screenshot of your code and pull it up your phone's Gallery
Print out your code - on a piece of paper, a business card or a sticker
Your company may be able to integrate your code into the billing process by printing your code on the customer receipt
Save your QR code to your Apple or Google Wallet
