I believe UPI of India and Pix of Brazil actually cross absorb features from each other which is nice to see.

UPI is getting from 1st December a way to send payments by phone number or random number(key) which I believe are partly inspired from Pix. Earlier phone number lookup was a layer on top of the UPI built by the fintech companies and now it will be part of the base system.

Now that UPI's operator NPCI is focusing on cross border transactions, some day Pix and UPI can interoperate. UPI is already integrated with Singapore's payment system and similarly in discussions with few other countries.
