Google Wallet provides fast & secure access to everyday essentials like cards, passes/tickets, tap & pay, and much more. After GPay was closed in the U.S. 2 months back, Google Wallet took its place. Now, it is also seen on the Google Play Store along with top Indian bank, airline, and cinema chain integrations. Thus, Google Wallet is expected to come to Indian users soon.
Recently, Google Wallet app showed screenshots of Air India, SBI, and PVR INOX. The Air India card showed a boarding pass with flight status, ticket details, and a QR code. SBI focused on loyalty perks showing reward points earned. Besides, the PVR INOX card had movie ticket details. However, after the Google Wallet India Launch news broke, Play Store removed these screenshots and replaced them with U.S. ones.
One more reason why Google Wallet can come to India soon is that this app works when you download (sideload) its APK and install it. Working involves adding credit/debit cards and using them for tap & pay via NFC powered smartphones. Moreover, @SnippierJoker's Google Wallet account showed Indian Oil rewards and @some1anywhere got it preloaded with Samsung Galaxy M34 for tokenized credit/debit cards.
In other countries where Google Wallet is live, the company has integrated GPay in it. However, Google Pay in India is expected to continue along with Google Wallet as a separate app because Google Pay is a crucial app for Indian users with millions of transactions daily (NPCI reported 5+ billion transactions valued at $83+ billion in March) behind Walmart’s PhonePe.
Peers such as PhonePe, Paytm, Mobikwik, PayZapp, etc. have got their digital wallets inside their payments app itself so it will be interesting to see how Google Wallet will prove fruitful if it launches as a standalone app.
I guess UPI lite works the same way. Don't see what a wallet can add to this.
