• The digital credentials API is a unified and secure framework for apps and websites to request verifiable proof of age and identity.
• Developed in collaboration with ecosystem partners in the W3C.

• Upcoming use cases include account recovery, travel, government services, online health services, and verified profiles.

NFC Tap to Pay

• Google Wallet is enabled for NFC tap to pay.
• Requires an NFC-enabled device and a terminal with Google Pay enabled.
• Users can open Google Wallet, select a credit card, and tap to pay.

Google Pay vs. Google Wallet

• Google Wallet is a container for digital IDs, debit/credit cards, transit cards, loyalty cards, event tickets, etc.
• Google Pay is a payment service that processes transactions.
• Users can pay with Google Pay even without Google Wallet (e.g., tapping a physical credit card).
• Google Wallet allows users to choose a credit card and tap to pay using Google Pay.

Google Wallet in India

• Google Wallet is available in India but initially launched without payment methods (credit/debit cards).
• India was the first country in the global expansion to launch a "passes first" wallet.
• This was due to the complexities of issuing credit/debit cards in a digital wallet.
• Google is working on adding payment method features to Google Wallet in India.
• The Google Pay app is very popular in India and has some overlapping features with Google Wallet.

Google Wallet API

• Developers can create passes that can be added to Google Wallet.
• The Google Wallet API is available through Google Cloud.
• Requires Google Cloud credentials for authentication and authorization.
• The Google Wallet API is free to use but requires enabling it in the Google Cloud Console.
• developers.google.com/wallet/events is the URL for past and upcoming Google Wallet events.

Adding Items to Google Wallet

• Users can add items to Google Wallet by scanning a QR code or barcode, or by using the "Add to Google Wallet" button.
• The "Add to Google Wallet" button is the preferred method because it indicates an integration provided by a developer, allowing for dynamic updates (e.g., loyalty points, flight information).
• The QR code/barcode scan is a static image and does not provide real-time updates.
• Gemini AI is used to recognize and add items to Google Wallet via the camera.

Security of Google Wallet

• Google Wallet stores credentials, event tickets, boarding passes, and loyalty cards in a safe and secure way.
• Security is a top priority.
• Multiple layers of authentication are used to protect private information.
• Users can enable biometric security (e.g., fingerprint) for authentication.

Rotating Barcodes and QR Codes

• Google Wallet supports rotating barcodes and QR codes for enhanced security.
• The secret keys for rotating barcodes and QR codes are not shared with the user or the phone.
• The phone does not necessarily need to be online to show a valid barcode.
• The Google Wallet API documentation should be followed for implementation details.
• The algorithm and frequency of barcode changes are shared with Google Wallet.
• Google's servers and the Google Wallet app perform computations to validate the barcode at a given time.

Hotel Keys and NFC Tags

• Google Wallet can integrate with NFC tags and cards, such as hotel room keys.
• Requires integration with the hotel chain and the specific key reader.
• Some hotel chains already issue digital keys to Google Wallet.
• Companies can also issue corporate badges as digital passes in Google Wallet.

Google Wallet and AI Assistants

• The speaker acknowledges the potential for integrating AI assistants with Google Wallet.
• Potential use cases include asking about loyalty points or flight information.
• Security and privacy are top concerns when considering such integration.
