When you withdrawal from PayPal (or at least Venmo), doesn't it go through an ACH?

Which is why PayPal can't be faster than ACH.

Neither does Ripple, which is the technology in question in this subthread.

Ripple is a member of NACHA: https://ripple.com/insights/ripple-labs-joins-mainstream-nac...

There is huge potential with what Ripple is doing, and their technology very much has a lot to do with ACH and cash settlement. Apologies if I was being an ass. I'm just really excited about Ripple and how I think their technology can transform the entire electronic movement of money. No more waiting days for cash to settle... it literally takes seconds. It's pretty amazing to see it in action.

You are so right, Ripple is one of the only companies trying to revolutionize how payments work by creating interoperability between different payment networks and working with banks. What they are trying to do is extremely ambitious... if they can pull it off then oh man, not sure what to say. It's like trying to predict Facebook pre internet.....

I do wonder how long until some regulators decide Paypal is a bank.

About 10 years ago.

That’s why PayPal Europe S.a.r.l. et Cie s.c.a. is a registered bank.
