Secure checkout infrastructure

RadbKao™ checkout is powered by Shopify and participating payment providers. The payment methods shown at checkout may vary according to location, currency, device, and current provider availability.

Authorization and fraud prevention

Orders are subject to payment authorization and reasonable fraud-prevention review. A bank or payment provider may request verification, decline a transaction, or place a temporary authorization hold. RadbKao™ does not control an issuer’s approval decision or the time required to release a hold.

How transaction data is handled

Payment-card details are transmitted to and processed by participating payment providers using their own security controls. RadbKao™ does not store complete payment-card numbers in its own store systems. Because no online system is entirely risk-free, customers should use trusted devices and networks and protect their account credentials.

Pricing and charges

The product price, discount, shipping charge, applicable tax, and final order total are displayed before payment is submitted. Currency-conversion charges, foreign-transaction fees, installment charges, or other issuer fees are determined by the customer’s provider.

Payment concerns

If a payment is declined, verify the billing information, available funds, issuer restrictions, and any authentication request. If two pending authorizations appear, contact the issuing bank; one entry may be a temporary hold rather than a completed duplicate charge.
