Many of you are probably familiar with near instantaneous money 
transfers using Venmo or Paypal. And while we discussed next-day ACH 
transactions in the textbook, in 2017, an interbank payment system was 
unveiled, the real-time payment (RTP) network.
 While only 130 banks out of the more than 9,600 financial institutions 
in the U.S. have adopted the system, these adopting banks cover 60 
percent of demand deposit checking and savings accounts. Several 
challenges have prevented the adoption of the RTP system. For example, 
businesses do not seem to be concerned about speeding up payments by one
 day, especially in the current low interest rate environment. The biggest hurdle appears to be infrastructure, but expect this hurdle 
to be reduced when Jack Henry & Associates and Fiserv come online 
later this year. But the RTP system does provide other perks, including 
24/7/365 access, instant confirmation, and settlement finality, meaning 
the sending bank can't revoke or recall a payment.
