Re:Amazon to stop accepting UK Visa credit cards by gtirloni on Wednesday November 17, 2021 @06:53AM (#29251838)
Brazil has gone that route with PIX [0]. It's a fund transfer system with realtime confirmation. Many e-commerce stores accept it besides debit/credit, they can confirm the payment almost instantaneously and they usually give discounts if you use PIX instead of debit/credit (3-10%).

Also, paying at stores, clinics, doctors, etc.. all done with PIX nowadays. Very few people are carrying cash these days. Very few clinics had a payment machine to accept debit/credit cards and now with PIX they have no incentive to do so anymore.

To transfer funds, you can specify the user's ID (which can be a phone number, national tax identification or some random string the user creates). To pay for purchases, you usually scan a QR code or copy a payment string using your bank's app/website. It's very convenient.

Interesting. Is having a brazilian bank account a prerequisite to use PIX?
