I do not know how the application process for Apple card is handled in the US but if I think Apple buying Credit Kudos is their first steps into trying to get Apple card into the UK and Europe, what concerns me is that Credit Kudos is currently registered with the FCA as an approved AISP which means they are allowed to have access to UK and European customer banking data when the customer agrees to allowing them to have access to their banking data and we know this will happen because when applying for a card a credit referency agency will request that you provide them with the authority to access your banking data so they can make an informed decision as to whether to provide you with the card or not. Usually this checking/verification process is handled by a third party referencing agency who whilst being allowed access to banking data as part of the companies agreed signup conditions by the FCA, this banking data is not passed onto other company that is requesting the check to be done. All the company gets is a yes or a no from the reference agency. But with Apple buying Credit Kudos who already have been approved by the FCA this means Apple will have access to a persons banking data, basically their banking history, what money has come into their account and what money has been going out. Thus, if someone in the UK or Europe was to apply for a Apple card, Apple will know exactly that persons full banking history because their banks statements will show exactly what they have been doing, it will show all the persons direct debits and standing orders, the lot.
Question people are going to have to ask themselves is do they want Apple to have all this knowledge about a persons banking behaviour?
