Excuse me, could you please explain to me how I can go about scanning a Coinbase QR code? I've heard that it's a quick and secure way to transfer cryptocurrency, but I'm not entirely sure how to proceed. Could you walk me through the steps, perhaps starting from the Coinbase app itself? It would be greatly appreciated if you could also highlight any potential pitfalls or security concerns I should be aware of when scanning QR codes. Thank you in advance for your help.

What are the advantages and disadvantages of this approach? Does it enhance user experience or introduce any potential security risks? Furthermore, are there any standards or best practices that should be followed when generating and scanning BIP21 QR codes?

I'm wondering, is it possible to send Bitcoin using the same QR code multiple times? I've noticed that many wallets and exchanges provide QR codes for receiving payments, but does this mean that the code remains valid indefinitely? I'm concerned about the security of reusing the same code and whether it could potentially lead to any vulnerabilities or risks. Additionally, I'm interested in understanding how QR codes work in the context of cryptocurrency transactions and whether there are any best practices to follow when using them for payments. Any clarification or advice on this matter would be greatly appreciated.
