Can I send Bitcoin with the same QR code?
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 <a href="https://www.btcc.com/en-US" title="cryptocurrency">cryptocurrency</a> 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.

How does a QR code work with a bitcoin wallet app?
Could you elaborate on how a QR code interfaces with a <a href="https://www.btcc.com/en-US/academy/research-analysis/bitcoin-btc-price-prediction-2023-2025-2030-is-btc-a-good-investment" title="Bitcoin">Bitcoin</a> wallet app? I'm curious about the underlying process when someone uses their phone's camera to scan a QR code for a bitcoin transaction. Does the QR code simply encode the bitcoin address, or does it include additional information like the amount to be sent? What happens once the code is scanned? How does the app verify the code's authenticity? I'm also interested in knowing if there are any security measures involved in this process to protect users' funds. Could you provide a step-by-step explanation of the entire process from scanning the QR code to completing the transaction?
