# Accept offline payments Accept payments when you have internet connectivity issues. > #### Cellular-enabled readers > > If you’re using a cellular-enabled reader like the Stripe Reader S710, see [Network transitions on cellular readers](https://docs.stripe.com/terminal/features/operate-offline/network-transitions.md) to understand how the reader transitions between WiFi, cellular, and offline mode. If you have internet connectivity issues, Stripe Terminal allows you to store payments locally on your POS device or smart reader. When a network connection is restored, the SDK or smart reader automatically forwards any stored payments to Stripe. From your application’s perspective, the payment collection process is similar to operating online. While offline, the smart reader or SDK securely stores the payment information and automatically forwards the stored payments when connectivity is restored. The SDK allows you to handle offline-related events using callbacks to your application. ## Availability ### Payment methods | Payment Method | Supported | | --- | --- | | Visa | ✓ Supported1,2 | | Mastercard | ✓ Supported1,2 | | Discover | ✓ Supported1,2 | | American Express | ✓ Supported1,2 | | China UnionPay | ✓ Supported1,2,4 | | JCB | ✓ Supported1,2,4 | | Maestro | ✓ Supported1,2,4 | | eftpos | ✓ Supported1,2,3,4 | | Cartes Bancaires | ✓ Supported1,2,3,4 | | NYCE, PULSE, STAR | - Unsupported | | girocard | - Unsupported | | Interac | - Unsupported | | QR code payments | - Unsupported | 1 Physical cards and NFC-based [mobile wallets](https://docs.stripe.com/payments/wallets.md) are supported.

You can safely reboot the reader, even with stored offline payments. After you reboot the reader and it reconnects to the internet, you can connect your POS application to the reader. The reader then resumes forwarding any remaining stored payments. A high-level diagram that shows how offline payments are stored.
