Super investor Marc Andreessen, cofounder of Andreessen Horowitz and board member for companies like Facebook and Hewlett-Packard believes a kind of financial ‘apocalypse’ is coming. And its name is Apple Pay.

“Apple Pay is the thing that is freaking out all the financial services companies right now,” Andreessen told Bloomberg’s Emily Chang during an interview in San Francisco on Wednesday. The new service will allow users to pay for stuff with an iPhone 6 or Apple Watch, either in physical shops or in apps, simply by touching the fingerprint scanner, called Touch ID.

“Apple’s showing up to the party and saying, ‘We’re going to now be in the center of payments’ has caused kind of like a collective heart attack,” he said. “And by the way, not just Apple but presumably Google … everybody assumes that Google will respond to Apple Pay and that Google Pay will work much the same way with Android,” Andreessen says.

Apple Pay will presumably be so safe and easy to use that people could easily adopt it. If that’s the case, it will insert Apple in the middle of the massive $4 trillion credit card industry. Apple has already convinced some of the biggest credit card companies and banks to support Apple Pay including Visa, MasterCard, American Express, and banks like Bank of America, Capital One, Chase, Citi, and Wells Fargo.

It’s “surprising … how many things don’t change with Apple Pay,” Andreessen says. “It’s very clever. It’s very cleverly done. It just inserts Apple into the middle of the existing system, which is why they’re all so freaked out.”

Apple has promised that Apple Pay will go live in October. We expect to hear more about Apple Pay at Apple’s event on Thursday, when it announces its new lineup of iPads and Macs.
