Key Takeaways

  • Selling raw cardholder data to third parties produces negligible revenue for major retail banks.
  • Businesses resist payment processing fees but spend heavily from marketing budgets to acquire customers.
  • Cardlytics distributed over $100 million to issuing banks in 2020 by selling merchant-funded offers inside banking apps.
  • Block uses Cash App Boosts to route consumer spending directly to merchants, funding discounts well above standard interchange rates.

The Real Monetization of Financial Touchpoints

Many consumers believe their banks quietly generate billions by selling transaction histories to data brokers. Patrick McKenzie points out that this model barely registers on a bank's income statement. Raw transaction data is messy, heavily regulated, and difficult for third parties to turn into clear returns. Selling a static file of customer habits does not command high pricing.

Instead, banks monetize attention by selling deterministic customer acquisition. Retailers constantly search for ways to divert shoppers from competitors. A coffee chain or a big-box retailer will fight credit card interchange fees that cost them two or three percent per transaction. Yet that exact same retailer will eagerly pay fifteen percent to win a customer who usually shops next door.

“One insight the industry had is that there is a limit to businesses' desire to pay for payment acceptance, but a much higher willingness to pay for customer acquisition,” McKenzie notes. “As technology has allowed credit card companies tight loops to their customers, they are increasingly attempting to nudge purchase behavior in provable ways, then invoice businesses for a portion of the marginal revenue driven.”

Why Marketing Budgets Beat Payment Rails

This dynamic changes the economics of consumer software. If you run a payment rail, you are trapped in a low-margin commodity race against regulated interchange caps. If you run an ad network attached to a payment method, you tap into corporate marketing budgets.

Consider Cardlytics, the platform powering merchant rewards inside digital banking interfaces. “Those are administered by a publicly traded company called Cardlytics, which charges the likes of Starbucks to drive them business, pays the customer incentive out of that marketing spend, and also pays the bank for lending them the customer relationship,” McKenzie explains. “It's real money: they paid banks more than $100 million back in 2020.”

Block applies the exact same model to Cash App Boosts. When Cash App gives a user ten percent off at a coffee shop, that discount is not financed by a tiny payment processing fee. The merchant funds the discount directly from their customer acquisition budget because the platform guarantees foot traffic.

“Much like Google and Facebook, issuers can demonstrate to the most sophisticated organizations on the planet that they can deterministically influence actual purchasing behavior,” McKenzie explains. “That's easier to sell than a CSV file, and worth more to businesses.”

What to Do With This

Audit your product's monetization strategy before you pitch payment fees or data licensing. If you hold user attention at the exact moment of a purchase decision, package that touchpoint as a targeted customer acquisition channel for vendors. Build a simple pilot offer with one merchant this week where they pay you a success fee on verified sales instead of a flat referral fee.
