Banks verify purchases using a combination of transaction history, location patterns, and fraud detection algorithms. When a purchase is made, the bank's system checks for unusual activity based on previous spending behavior and geographic location. Security features like CVV codes, OTP (One-Time Password), and PIN numbers also help in verification. If something seems off, the bank may contact the customer for confirmation or temporarily freeze the account to prevent fraud.
