Securely Take Payments in a React Native App
summary
A working React Native Order Ahead app shows Square In‑App Payments SDK handling card entry UI that sends tokenized nonces directly to Square so the app never sees PAN/CVV; catalog items come from Square Catalog API and a Google Cloud Function backend receives the nonce to create an order. Notes: Expo doesn’t support native modules, App ID ties tokens to one app, and processing costs are typically 2.9% + $0.30 (about 27% cheaper than Play billing).
