Common Causes of Toast Not Taking Payments

How to Fix Toast POS Not Taking Payments
1. Restart the Toast POS Terminal
This is the fastest fix for payment failures and reader activation bugs.
- Hold the power button
- Select Restart
- Wait for Toast to fully reboot
- Retry a payment
If the terminal seems frozen, see our Toast POS Frozen guide.
2. Reset the Toast Card Reader
A frozen or desynced reader is one of the top reasons payments won’t initiate.
- Unplug the reader (if wired) or turn it off/on
- Reconnect via the Toast POS app
- Confirm the LED indicator lights up
- Try chip, tap, and swipe again
If the reader is completely unresponsive or disconnecting, review your Wi-Fi next.
3. Check Your Network & Wi-Fi Stability
Payments depend heavily on real-time connectivity. Even momentary drops can cause failures.
- Verify you’re on the correct secured network (not guest Wi-Fi)
- Move closer to the router
- Restart the router if all stations are slow
- Check if KDS screens are lagging or missing orders
If multiple stations are having issues, see our Toast KDS Not Working troubleshooting guide.
4. Try a Different Payment Method
Sometimes the issue is card-type specific.
- Try chip → tap → swipe in that order
- Attempt a manual card entry (if enabled)
- Test with a different customer card
5. Confirm Payment Settings in the Toast Dashboard
A disabled merchant setting can block payment processing.
- Log into your Toast Dashboard
- Check that credit card payments are enabled
- Verify that no permission changes were made
- Check for alerts from Toast regarding payment delays
6. Update the Toast POS App
Outdated versions frequently cause payment failures, especially after system updates.
- Restart the device
- Open Google Play / Toast device app manager
- Search for Toast POS
- Tap Update
7. Reboot the Entire Toast System (Last Resort)
If payments still fail, a full system reset may be necessary.
- Restart all terminals
- Restart routers and access points
- Restart the Toast payment device (if separate)
This typically resolves multi-station failures.
