FAQ & SUPPORT
Common questions from merchants, installers, and users.
Device & Connectivity
Unable to enter the device activation interface or PAYDAO App interface?
Please check your network connection and make sure you are not in a restricted country or region. The PAYDAO network requires an active internet connection to process transactions.Transactions
What should I do if a transaction fails?
Please check the network connection, make sure the card has been activated and has sufficient USDC balance, then place the card close to the NFC area and keep it still for 1–5 seconds. If the issue persists, contact support.What should I do if a transaction keeps showing "Processing"?
The transaction may be waiting for network or blockchain confirmation. Please wait patiently and avoid repeated operations. During times of Solana network congestion, confirmations may take longer than usual.Will funds be deducted if a transaction fails?
No funds will be deducted unless the transaction is marked as successful. Users can check their App balance or verify the transaction status on the Solana blockchain explorer.Balance is not updated after a top-up?
Blockchain confirmation may take longer during network congestion. Please wait patiently and pull down to refresh the App. If the balance still does not update after 10 minutes, contact support.Payments & QR Codes
Is Scan-to-Pay supported?
Yes. Users can scan the QR code displayed on the POS terminal with any wallet that supports Solana Pay. Note: QR payments do not generate $PAY rewards for either Installers or Users. — only NFC tap payments consistently trigger the Pay-as-Mining mechanism.How are refunds handled?
Merchants and users can verify the payment through the on-screen receipt or by checking the blockchain transaction record. Because PAYDAO transactions are on-chain, refunds are handled offline between the merchant and user — they should communicate directly to confirm the refund method (e.g. cash, bank transfer, or a manual USDC send).Contact Support
