It's important to realize the time value of money. "Tech" means faster, easier transfers and processing. This is great for consumers --- but not so great for banks. Banks make a lot of money from "float" --- the lag time between the initiation of a transaction and it's actual completion. The delay between the point in time where money is withdrawn from the sender's account until it is actually credited to the receiver's account. In many cases, this is a day or more in the US. Bottom line --- most US banks have billions of dollars just "floating" on their books --- continuously. This is someone else's money that the *bank* can earn free interest on. "Tech" (aka instant transactions) threatens to eliminate this source of income for banks.
