If you already have a Direct Debit set up on your Argos Card account, this will transfer across to your Argos Pay account automatically, so you won't miss a payment. See the FAQ Will there be any changes to my Direct Debit? for more information on this. We'll also send you further information by email or post about your Direct Debit before your Argos Card account is updated in April.
If you usually pay by Standing Order, you'll need to update the bank details and payment reference with your bank as we cannot do this for you. You should also make sure to check your statement each month to ensure the standing order amount will cover your minimum monthly payment. There's more information here about these and other payment options, once your account has updated to Argos Pay.
