P-to-P payments

The rapid advancement of social media platforms into the payments and finance markets, as well as millennials' devotion to apps like Venmo, were major factors driving a 47% increase in the U.S. digital person-to-person payments market last year.

When Zelle launches, it will not allow users to share information about their payments with other folks in their network. That decision puts the P-to-P service on a different course than Venmo, its fast-growing rival.

The upcoming launch of Zelle gives Chase, B of A, Wells Fargo and other large banks an opportunity to correct their past mistakes.
