As a <a href="https://www.btcc.com/en-US" title="cryptocurrency">cryptocurrency</a> enthusiast and someone who keeps abreast of the latest financial technologies, I'm curious about the integration of QR codes into Bitcoin payments. Could you elaborate on how QR codes specifically facilitate the receipt of Bitcoin? Do merchants simply display a QR code that customers scan using a Bitcoin wallet app on their smartphone? What are the advantages of this method compared to traditional payment systems? Also, is it safe to use QR codes for Bitcoin payments, and what measures should users take to ensure security?
