V400M Device is in Offline Mode

When Toast enters offline mode, the card readers will automatically store the processed payment locally on the reader. When the internet returns, the devices will automatically sync with the host. The pending icon indicates that there are payments that the terminal hasn't been able to send to the device host for completion (capture and settlement).

Device is in Tamper Mode

Re-board to a New Location 

For seamless transactions on your Toast Flex, your card reader must be correctly linked to the device store associated with your Toast account.

If your card reader isn't set up correctly:

• Payments won't initiate.
• An error will show on the card reader or Kiosk: "The card reader isn't set up for this location - Pair it correctly or contact Toast."
• Under device setup in Flex, Card Reader Status will display 'Device registered to another location'. Payments are only possible when it shows 'Connected'.

If you need to use your device elsewhere, our can re-board your reader to a new location. Please contact them for assistance.
