What card networks are supported?
Glomo supports major card networks such as Visa, Mastercard and Amex.
How secure are card payments?
All card transactions go through 3D Secure (3DS/OTP) where mandated, ensuring an extra layer of protection. Glomo is PCI DSS compliant and adopts industry leading practices in storing data.
How long does it take for refunds to reflect?
Refunds initiated by Glomo usually take 4–7 business days to reflect on the customer’s card statement, depending on the issuing bank.
Why was a payment marked as failed even though the customer was charged?
If Glomo does not receive the authorization response in time, the payment may be marked as failed. In such cases, once reconciliation confirms the success, Glomo automatically refunds the payment.
Can customers retry a failed card payment?
Yes. Customers can retry the payment by re-entering their card details or using an alternative card. If the failure was due to bank-side issues (e.g., insufficient funds), retrying after resolving the issue should succeed.
Are there transaction amount limits?
Yes. Glomo currently enforces a maximum transaction limit of USD 16,000 (or the equivalent in other currencies) for card payments. In addition, individual banks and card networks may impose their own daily or per-transaction limits. If a transaction exceeds these limits, the payment may be declined by the bank or card issuer, even if it is within Glomo’s limits.
