The new feature, to be launched in the coming months, makes any Android device capable of making digital payments with credit and debit cards by using their camera to scan dynamic codes in payment machines.
This feature was designed and developed considering people's needs in countries like Brazil, where a significant portion of smartphones do not have NFC, the technology used in contactless payment methods. It will bring the safety and ease of Google Wallet’s digital payments to more people.
