What Card Account details must I use for particulars, code and reference?

BALANCE TRANSFER

Please provide the same payment details used when making a payment to your non-Q Mastercard credit card. The particulars, code & reference fields should have all necessary information to ensure that the payment we make to your other card(s) is successfully completed. If you’re unsure of what this information is, please contact your other card provider directly to confirm before completing your Balance Transfer request.
