When a payment is declined on Clover POS, the error almost always originates from the customer's issuing bank — not from Clover itself. Understanding the decline message helps you guide customers appropriately and avoid lost sales.
Step-by-Step Instructions
- Note the exact decline message displayed. Common codes: 'Do Not Honor' (generic bank decline), 'Insufficient Funds,' 'Invalid Card Number,' 'Card Expired,' and 'REJECT 203' (security hold).
- Politely inform the customer that the decline came from their bank, not your terminal. Never attempt to re-swipe a declined card more than twice.
- Ask the customer to use an alternative payment method: a different card, mobile pay (Apple Pay, Google Pay), or cash.
- If a chip card is declining, try the swipe fallback. If a tap is declining, insert the chip instead.
- For 'Invalid Card Number' errors, have the customer manually enter the card number using the keypad on the Clover device.
- If multiple cards from different customers are declining, the issue may be with your internet connection or batch settlement — check your network immediately.
📌 Important Note: Clover does not have access to the reason a bank declines a card. Only the cardholder's issuing bank can provide that information to the customer.
Frequently Asked Questions
It is a generic decline code issued by the customer's bank, often triggered by suspicious activity detection, daily limits, or a frozen account. The cardholder should contact their bank directly.
If all cards are declining, check your internet connection, ensure your batch is not stuck, and verify your merchant account is in good standing with your processor.
No. Clover cannot override an issuing bank's decline decision. Attempting to force a declined card can result in chargebacks and processor penalties.
