Fun fact, before Pix, every bank was trying out different digital wallet solutions. It was a pain to go to a store and realize they support Bank A's digital wallet, which, not surprisingly, doesn't interoperate with Bank's B. I went to buy açai at a shop one day and didn't have cash. Only way I could pay was with Itau's iti, but I only had money in my PicPay account. Pix was a godsend that saved us from the thousands of different, non-interoperable digital wallets the fintechs were creating.
