amount refunded must not exceed the original purchase amount

to the cardholder within business days
• Refunds must be returned to the same account that the original purchase was
sourced from
• If the refund cannot be matched with the original purchase and is within the 0 days
then the merchant must not provide a refund in any other form; eg. paper transaction
• The cardholder must dispute the transaction upon returning to mainland China.
Auth IDs for matching Pre-Authorisations & Pre-Authorisation Completions
• UnionPay does not provide the same Auth IDs for corresponding Pre-Authorisation and
Pre-Authorisation Completion. Therefore the transaction receipts will show different
Auth IDs.

allowed for up to 0 days from the date of the original Pre-Authorisation
• The merchant must enter the Auth ID, RRN and the Auth date from the original
Pre-Authorisation to enable the cancellation to be matched with the original
Pre-Authorisation
• The cancellation requires both PIN and signature verification.
Pre-Authorisation Completion Cancellations
• UnionPay allows the cardholder to cancel the Pre-Authorisation Completion
• This is only allowed for the same settlement day as the Pre-Authorisation Completion
• The merchant must enter the Auth ID, RRN and the Auth date from the
Pre-Authorisation Completion to enable the cancellation to be matched
with the Pre-Authorisation Completion
• The cancellation requires both PIN and signature verification.
