Along with Google‘s announcement of an AI research center, its local language translation with Google Lens, and a phone number for Google Assistant, today the search giant announced Tokenized payment cards in the Google Pay app in India.

With this feature, you’ll be able to load your card in the Google Pay app and pay for stuff online and offline (via NFC on Android). With this, you won’t need to provide your actual debit card number or a physical card. The company claims this method is more secure than using your card.
