The first major upgrade in electronic payments since the Automated Clearing House (ACH) was created 40 years ago and Check 21 launched in 2001 is being implemented by The Clearing House (TCH), a private firm owned by 24 of the largest banks. Commercial real-time payments began in the U.S. in November 2017 and by the end of 2018 had reached 11 large banks of the 24 that are owners of TCH. The banks participating in real time payments can all receive payments and some can also send. So far they are working with corporate payments. Source.
