Do not share one-time codes
OTP and 3DS messages should only be handled by the account and card owner. Sharing codes with an agent or recharge seller creates account and payment risk.
Keep a verification log
Record the time, merchant, amount, card status and result. This makes future online service, Google or SaaS subscription support much cleaner.
Card rules note
RamboCard is a virtual card and issuing API platform. It does not represent developer service, Google, online service or other merchants. These guides help users prepare their own payment method, billing evidence and transaction records; they do not promise approval and do not encourage bypassing regional, verification or merchant rules.
