A Scan to Pay app is a mobile application that allows users to make payments by scanning a QR code at a merchant's store, website, or peer-to-peer transaction. These apps are widely used due to their ease of use, security, and ability to support multiple payment methods. However, they also have drawbacks, including fraud risks and technical limitations.

Transactions may fail in areas with weak or no internet coverage (e.g., rural areas, underground subway stations).
Offline payment options are rare, although some apps allow preloaded balances for limited offline use.
2. Security Risks & Fraudulent QR Codes
Fraudsters can create fake QR codes that redirect payments to unauthorized accounts.
Some cybercriminals replace legitimate QR codes with their own, tricking users into transferring money to scammers.
Phishing attacks may involve sending fake payment links that mimic real apps.
Users should verify merchant QR codes and use official apps from trusted providers.

Older smartphones may lack QR-scanning capabilities or struggle with app performance.
Some apps require specific OS versions (e.g., Android 8.0+ or iOS 12+), leaving out users with outdated devices.
If a phone’s camera is faulty, scanning QR codes becomes difficult or impossible.
4. Technical Glitches & System Downtime
Some scan-to-pay apps crash, freeze, or face server issues, causing failed transactions.
If the payment gateway experiences high traffic (e.g., holiday shopping season), payments may take longer to process.
Some users experience double deductions due to app glitches, requiring manual refund requests.
5. Limited Merchant Acceptance
Not all merchants, especially in remote areas, accept QR-based payments.
Some businesses only support specific scan-to-pay apps, requiring users to have multiple payment apps.
Cash is still dominant in many small-scale businesses, forcing users to carry backup payment methods.

Payment gateways may experience congestion during busy hours, leading to delays or failures.
Users may need to retry transactions multiple times, causing frustration.
Some banks and financial institutions restrict large transactions, requiring extra authentication steps.

Companies may share or sell user data for targeted advertisements.
Users must carefully review app permissions and avoid apps with vague privacy policies.
8. Battery & Storage Consumption
Requires a charged smartphone to complete transactions, which can be an issue if the battery runs out.
Some apps take up a lot of storage and RAM, leading to slow device performance on older phones.
Regular updates may consume mobile data, affecting users with limited internet plans.
9. Regulatory & Legal Limitations
