The Justice Department filed an antitrust lawsuit on Thursday, alleging that Visa's proposed acquisition of Plaid would limit competition.
In a statement, the DOJ said, "Visa seeks to buy Plaid — as its CEO said — as an 'insurance policy' to neutralize a 'threat to our important US debit business.'" The argument seems to be that Plaid, which helps connect financial companies to each other, would help Visa maintain a monopoly in online debit transactions.
The suit could halt the $5.3 billion acquisition, which was set to be one of the biggest fintech deals yet. In a statement, Visa said the the DOJ's attempt is "legally flawed and contradicted by the facts."

The future of computing at the edge: an interview with Intel’s Tom Lantzsch
An interview with Tom Lantzsch, SVP and GM, Internet of Things Group at Intel
An interview with Tom Lantzsch

Senior Vice President and General Manager of the Internet of Things Group (IoT) at Intel Corporation
Edge computing had been on the rise in the last 18 months – and accelerated amid the need for new applications to solve challenges created by the Covid-19 pandemic. Tom Lantzsch, Senior Vice President and General Manager of the Internet of Things Group (IoT) at Intel Corp., thinks there are more innovations to come – and wants technology leaders to think equally about data and the algorithms as critical differentiators.
In his role at Intel, Lantzsch leads the worldwide group of solutions architects across IoT market segments, including retail, banking, hospitality, education, industrial, transportation, smart cities and healthcare. And he's seen first-hand how artificial intelligence run at the edge can have a big impact on customers' success.
Protocol sat down with Lantzsch to talk about the challenges faced by companies seeking to move from the cloud to the edge; some of the surprising ways that Intel has found to help customers and the next big breakthrough in this space.
What are the biggest trends you are seeing with edge computing and IoT?
A few years ago, there was a notion that the edge was going to be a simplistic model, where we were going to have everything connected up into the cloud and all the compute was going to happen in the cloud. At Intel, we had a bit of a contrarian view. We thought much of the interesting compute was going to happen closer to where data was created. And we believed, at that time, that camera technology was going to be the driving force – that just the sheer amount of content that was created would be overwhelming to ship to the cloud – so we'd have to do compute at the edge. A few years later – that hypothesis is in action and we're seeing edge compute happen in a big way.
Jack Dorsey is so money: What Tidal and banking do for Square
Teaming up with Jay-Z's music streaming service may seem like a move done for flash, but it's ultimately all about the money (and Cash).
Jay-Z performs at the Tidal-X concert at the Barclays Center in Brooklyn in 2017.

It was a big week for Jack Dorsey, who started by turning heads in Wall Street, and then went Hollywood with an unexpected music-streaming deal.
Dorsey's payments company, Square, announced Monday that it now has an actual bank, Square Financial Services, which just got a charter approved. On Thursday, Dorsey announced Square was taking a majority stake in Tidal, the music-streaming service backed by Jay-Z, for $297 million.

Blockchain, QR codes and your phone: the race to build vaccine passports
Digital verification systems could give people the freedom to work and travel. Here's how they could actually happen.
One day, you might not need to carry that physical passport around, either.

Previously, Mike was the technology editor at Quartz, where he frequently wrote on robotics, artificial intelligence, and consumer electronics.
There will come a time, hopefully in the near future, when you'll feel comfortable getting on a plane again. You might even stop at the lounge at the airport, head to the regional office when you land and maybe even see a concert that evening. This seemingly distant reality will depend upon vaccine rollouts continuing on schedule, an open-sourced digital verification system and, amazingly, the blockchain.
Several countries around the world have begun to prepare for what comes after vaccinations. Swaths of the population will be vaccinated before others, but that hasn't stopped industries decimated by the pandemic from pioneering ways to get some people back to work and play. One of the most promising efforts is the idea of a "vaccine passport," which would allow individuals to show proof that they've been vaccinated against COVID-19 in a way that could be verified by businesses to allow them to travel, work or relax in public without a great fear of spreading the virus.

Eric Sager is an avid surfer. It's a fitting passion for the No. 2 executive at Plaid, a startup that's riding fintech's rough waters — including a rogue wave on the horizon that could cause a wipeout.
As Plaid's chief operating officer, Sager has been helping the startup navigate that choppiness, from an abandoned merger with Visa to a harsh critique by the CEO of a top Wall Street bank.
