Process UnionPay cards the same as you would other debit and credit cards, following the prompts on your terminal. If you experience one of the error messages below, perform an assisted UnionPay transaction. This option will guide you through additional steps required to recognize unique card attributes and assure the transaction is routed to the UnionPay network.
Make sure you know how to identify UnionPay cards. All UnionPay cards feature the red, blue, and green UnionPay logo. For more information, refer to How to Identify UnionPay Cards.
If you receive one of the following error messages, cancel the transaction and start an assisted UnionPay transaction.
INVALID CARD NUMBER
INVALID EXPIRY DATE PLEASE RETRY
NOTES:
UnionPay debit cards do not support account selection (chequing/savings). Even if the prompt appears, and the cardholder selects an account, the transaction will be processed using the default account.
UnionPay cards co-branded with Interac must be processed using the Interac brand.
First determine if the original transaction (Purchase or Pre-Auth) was assisted (see below). If the original transaction was assisted, then initiate an assisted transaction for the Refund, Pre-Auth completion, or Void.
Otherwise, process the transaction as you normally would. If needed, refer to Credit Transactions or Debit Transactions.
Look at the original receipt, either the cardholder copy or the merchant copy. If UNIONPAY is printed below APPROVED on the receipt, then the transaction was assisted by using the UnionPay function key or the UnionPay transaction menu.
