Google Wallet has announced the expansion of its digital hotel room key service through a partnership with Club Quarters, now available for Android users. This integration allows guests to add their hotel card keys directly into the Google Wallet app, enabling smartphone access to their rooms via NFC technology. Previously, digital room keys were only accessible through the hotel's app since 2017. Club Quarters claims to be the first hotel chain globally to implement this technology across its locations in the U.S. and U.K. This move reflects the ongoing trend towards digitalization and smartphone convenience in hospitality services.
