The Top of Wallet® Imperative for Card Issuers
Michigan State University Federal Credit Union placed its cards on file at the merchants its members already use, and recorded a 15% member opt-in rate, a 96% card placement success rate and a 12× return on investment (Strivve & MSUFCU Case Study, 2025). Those three numbers answer the questions every card issuer asks about card-on-file placement: how many cardholders will use it, how often it works, and what it returns against its cost.
They also point to a larger shift in where card programs win and lose. McKinsey's payments research puts it plainly: "Top-of-wallet status remains the primary objective — regardless of the nature of that wallet" (McKinsey & Company, The Future of Payments, 2024).
The card on file decides who earns the interchange
Every merchant account a cardholder keeps — a streaming service, a pharmacy, a mobile carrier's autopay — stores one default card. That card collects every recurring charge and every one-click purchase until someone changes it, and the issuer behind it earns the interchange revenue. Being that stored default is what Strivve calls Top of Wallet. The competition for it happens one merchant account at a time, and once a card is on file, it tends to stay there.
Every reissue resets the race
About 30% of the card accounts in an issuer's portfolio change number or expiration date, or close, every year, according to Visa's Account Updater documentation. Each change breaks the stored credential at every merchant where the old card was saved. The replacement takes days to arrive, has to be activated, and then has to be typed in again at each merchant by hand — while the cardholder's other cards keep working at checkout.
The cost shows up fast. Card spend falls by about 35% in the one to two months after a replacement, Ondot's CEO told PYMNTS in 2019. Whichever card fills that gap at checkout is the one that stays.
Account updaters keep your card where it already is
Visa Account Updater and Mastercard Automatic Billing Updater pass new card numbers to the merchants that ask for them. That protects transactions where your card is already saved, and nothing more. An updater does not place your card at a new merchant, make it the default anywhere, or win back the spend lost in the weeks after a replacement. Mastercard's own analysis of its top 200 card-not-present merchants (2015) found its updater addresses 33% of their declines, leaving two-thirds unaddressed.
Switching tools are worth offering. None of them adds card transactions.
Subscription management, bill pay switching and direct deposit switching all answer real cardholder demand. Look at what each one does to the card portfolio, though. Subscription management cancels recurring card charges. Bill pay switching moves the bills a cardholder already has, once, at account opening. Direct deposit switching moves money into the institution and generates no card transactions at all. Each is a cost center to run alongside a growth engine, not in place of one.
Card-on-file placement is that growth engine. It puts your card at the merchants your cardholders choose, at the moments they are already thinking about the card: activation, reissue and campaign launches.
How placement works
The cardholder picks the merchants and authorizes the placement once. Strivve's agentic AI then acts on the cardholder's behalf, navigating each merchant's account pages and saving the card as the payment method — work the cardholder would otherwise do by hand at every site. With CardLinks™, issuers deliver that flow through a personalized link in channels they already run, such as email, text messages and a QR code on the card carrier, with no digital banking integration required, and programs go live in weeks. Issuers that want placement inside their own app embed it with CardUpdatr™, the route MSUFCU took to its 12× first-year return.
