Plaid asks for your bank credentials, logs into your bank account, and obtains your banking data, such as balances, assets, transaction history, and debt. Visa wants to buy it all. Justice Department has sued.
Visa, the credit card network, is trying to buy financial technology company Plaid for $5.3 billion. The merger is bad for a number of reasons. First and foremost, it would allow a giant company with a controlling market share and a history of anticompetitive practices to snap up its fast-growing competition in the market for payment apps. But Plaid is more than a potential disruptor, it’s also sitting on a massive amount of financial data acquired through questionable means. By buying Plaid, Visa is buying all of its data. And Plaid’s users—even those protected by California’s new privacy law—can’t do anything about it.
Since mergers and acquisitions often fall outside the purview of privacy laws, only a pointed intervention by government authorities can stop the sale. Thankfully, this month, the US Department of Justice filed a lawsuit to do just that. This merger is about more than just competition in the financial technology (fintech) space; it’s about the exploitation of sensitive data from hundreds of millions of people. Courts should stop the merger to protect both competition and privacy.
Visa’s Monopolistic Hedge
The Department of Justice lawsuit outlines a very simple motive for the acquisition. Visa, it says, already controls around 70% of the digital debit card payment market, from which it earned approximately $2 billion last year. (Mastercard, at 25% market share, is Visa’s only significant competitor.) Thanks to network effects with merchants and consumers, plus exclusivity clauses in its agreements with banks, Visa is comfortably insulated from threats by traditional competitors. But apps like Venmo have started—just barely—to eat away at the digital transaction market. And Plaid sits at the center of that new wave, providing the infrastructure that Venmo and hundreds of other apps use to send money around the world.
According to the DoJ, a Visa executive predicted that Plaid would undercut its debit card processing business eventually, and that buying Plaid would be an “insurance policy” to protect Visa’s dominant market share. The lawsuit alleges that Plaid already had plans to leverage its relationships with banks and consumers to launch a new debit service. Seen through this lens, the acquisition is a simple preemptive strike against an emerging threat in one of Visa’s core markets. Challenging the purchase of a smaller company by a giant one, under the theory that the purchase eliminates future competition rather than creating a monopoly in the short term, is a strong step for the DoJ, and one we hope to see repeated in technology markets.
But users’ interest in the Visa-Plaid merger should extend beyond fears of market concentration. Both companies are deeply involved in the collection and monetization of personal data. And as the DoJ’s lawsuit underscores, “Acquiring Plaid would also give Visa access to Plaid’s enormous trove of consumer data, including real-time sensitive information about merchants and Visa’s rivals.”
Plaid, Yodlee, and the sorry state of fintech privacy
Plaid is what’s known as a “data aggregator” in the fintech space. It provides the infrastructure that connects banks to financial apps like Venmo and Coinbase, and its customers are usually apps that need programmatic access to a bank account.
It works like this: first, an app developer installs code from Plaid. When a user downloads the app, Plaid asks the user for their bank credentials, then logs in on their behalf. Plaid then has access to all the information the bank would normally share with the user, including balances, assets, transaction history, and debt. It collects data from the bank and passes it along to the app developer. From then on, the app can use Plaid’s services to initiate electronic transfers to and from the bank account, or to collect new information about the user’s activity.
In a shadowy industry, Plaid has tried to cultivate a reputation as the “trustworthy” data aggregator. Envestnet/Yodlee, a direct competitor, has long sold consumer behavior data to marketers and hedge funds. The company claims the data are “anonymous,” but reporters have discovered that that’s not always the case. And Finicity, another financial data aggregator, uses its access to moonlight as a credit reporting agency. A glance at data broker listings shows a thriving marketplace for individually-identified transactions data, with dozens of sellers and untold numbers of buyers. But Plaid is adamant that it doesn’t sell or monetize user data beyond its core business proposition. Until recently, Plaid has often been mentioned alongside Yodlee in order to contrast the two companies’ approaches, when it’s been mentioned at all.
Now, in the wake of the Visa announcement, two new lawsuits (Cottle et al v. Plaid Inc and Evans v. Plaid Inc) claim that Plaid has exploited users all along. Chief among the accusations is that Plaid’s interface misleads users into sharing their bank passwords with the company, a practice that plaintiffs allege runs afoul of California’s anti-phishing law. The lawsuits also claim that Plaid collected much more data than was necessary, deceived users about what it was doing, and made money by selling that data back to the apps which used it.
EFF is not involved in either lawsuit against Visa/Plaid, nor are we taking any position on the validity of the legal claims. We’re not privy to any information that hasn’t been reported publicly. But many of the facts presented by the lawsuits are relatively straightforward, and can be verified with Plaid’s own documentation. For example, at the time of writing, https://plaid.com/demo/ still hosts example sign-in flow with Plaid. Plaid does not dispute that it collects users’ real bank credentials in order to log in on their behalf. You can see for yourself what that looks like: the interface puts the bank’s logo front and center, and looks for all the world like a secure OAuth page. Try to think about whether, seeing this for the first time, you’d really understand who’s getting what information.
Many users might not realize the scope of the data that Plaid receives. Plaid’s Transactions API gives both Plaid and app developers access to a user’s entire transaction and balance history, including a geolocation and category for each purchase made. Plaid’s other APIs grant access to users’ liabilities, including credit card debt and student loans; their investments, including individual stocks and bonds; and identity information, including name, address, email, and phone number.
