Step 1: Authenticate the User

🔐 Enter the Name + PIN to unlock access — like stepping into your own digital VIP vault.

Step 2: /bank-transfer

💸 Transfer money from the sender to the receiver (don’t worry… no real money was harmed during this process 😂).

📉 The sender’s balance decreases 📈 The receiver’s balance increases (If only real banks processed transfers this fast 😭)

Step 3: Re-authenticate the Receiver

🔄 Log in again using the receiver’s details to confirm the updated balance.

FastAPI basically replies: “Good news… your money has officially left you!” 😂
