Nacha, the bank industry group that sets the rules for the network that connects every U.S. bank and credit union, has announced a new effort to achieve same-day electronic transactions. Under Nacha's proposal, payments will eventually be processed twice each weekday. But the overhaul would fall short of the near real-time systems that have been built in the United Kingdom, Mexico, Sweden and other countries -- and will also lag behind numerous proprietary real-time payment systems in the United States. The organization plans to phase in same-day capabilities in three stages, which they hope will assuage concerns raised opponents who derailed a similar effort in 2012 and give banks more time to make costly upgrades to their computer systems.
