Payment services from tech firms like Apple and Google risk squeezing out traditional banks and need monitoring. Authorities in France raised the concern that these firms can make money from these services but avoid much of the regulation, Bloomberg News reported.

The French authority also highlights access to near-field communication on smartphones used for contactless payment, an issue that has already triggered EU and Dutch antitrust probes and potential legislation to respond to banks’ complaints that Apple unfairly blocks their access on its devices. The companies that the French agency calls “les BigTech” are armed with “considerable financial power” to invest in new technologies and will have lower marginal costs compared to banks. Access to large volumes of data and processing power may allow them better assess customers financial health and offer them targeted services, the authority said. Integrating payments in other services allows them to offer a “customer journey” that can’t be matched or replaced easily by competitors, the authority said
