Tap n’ go: Android’s rumored ‘Tap to Share’ UI might’ve just broken cover

A new report highlights Google's "Tap to Share" feature, which includes a redesigned sharing menu that aligns with Android 16 aesthetics. Users will initiate the transfer process by overlapping their devices, which will emit a glow to indicate successful completion. The user interface features a straightforward sub-menu with three selectable options for sharing. The upcoming Galaxy S26 series will have dual antennas to support this feature. The process may utilize NFC technology, with potential future iterations using Wi-Fi or Bluetooth. The design of the sub-menu has been refined to match Android 16's visual elements.

This is the best Google Pay feature you’re not using in India

Google Pay's Tap to Pay feature, launched in 2020, allows contactless payments using NFC technology. Initially compatible with only two banks, it now works with most major debit and credit cards in India. Users can add their cards to Google Pay, and payments can be made by selecting the card and tapping the phone near a point-of-sale machine. The feature supports most Visa and MasterCard cards issued in India, while American Express cards are excluded. There are no transaction limits, and a PIN is required for high-value transactions. The setup process involves adding card details and authenticating via SMS. Tap to Pay can also be used internationally, except in China.

How Android Apps Are Adapting To The Rise Of Cross-Platform Digital Payments

Android developers are adapting to a rapidly changing global payments landscape, driven by user demand for seamless experiences across platforms, shifting regulatory frameworks, and the rise of cross-border transactions through mobile applications. This evolution is particularly relevant for international sectors like igaming, which often utilize alternative payment methods under offshore licensing. Developers are focusing on streamlined in-app experiences by adopting payment frameworks that enhance security and expedite verification processes. Over the past two years, payment standards have diversified, leading to the implementation of unified payment layers in Android apps to accommodate various tokens, cards, mobile wallets, and region-specific methods. The number of global mobile payment users is projected to reach 5.6 billion by 2025, highlighting the need for cross-platform support. Mobile wallets, NFC, and universal payment APIs are being integrated more deeply into the Android ecosystem, allowing for instant recognition of users' preferred wallets. Streaming platforms are adopting cross-platform billing strategies, while travel apps are implementing flexible frameworks to adapt to regional regulations. In online gaming, there's a focus on diverse payment options to meet international audience expectations. By 2026, Android applications are expected to feature more cohesive payment interfaces, increased biometric verification, and dynamic updates of payment methods based on user location and device capabilities.

Microsoft Security Keys May Require PIN After Recent Windows Updates

Microsoft announced an update for FIDO2 security keys on Windows 11, introducing a new prompt for users to set up a PIN during authentication. The rollout began with preview update KB5065789 on September 29, 2025, for OS Builds 26200.6725 and 26100.6725, and was completed with security update KB5068861 on November 11, 2025, for OS Builds 26200.7171 and 26100.7171. This update affects sign-ins where a Relying Party (RP) or Identity Provider (IDP) requests User Verification set to “Preferred” for keys without a PIN, in accordance with WebAuthn specifications. Users must now set up a PIN during authentication flows, not just during registration. To avoid PIN prompts, RPs or IDPs can set “userVerification” to “discouraged.” There is no option to roll back the changes.

Microsoft: Security keys may prompt for PIN after recent updates

Microsoft issued a notice to users about a new behavior related to FIDO2 security keys following Windows updates since the September 2025 preview update. This change affects devices on Windows 11 versions 24H2 or 25H2, where users may be prompted to enter a PIN during authentication. The adjustment aligns with WebAuthn specifications, which outline protocols for authentication methods, including PINs and biometrics. User verification can be categorized as discouraged, preferred, or required, with "preferred" necessitating a PIN setup if supported by the authenticator. The rollout began after the KB5065789 preview update and was completed with the November KB5068861 security update. Microsoft stated that after installing the September 29, 2025 update, users might need to create a PIN to sign in with a security key, even if it was not required during initial registration. This behavior occurs when a Relying Party or Identity Provider requests User Verification = Preferred during authentication with a FIDO2 security key lacking a PIN. Organizations can opt to adjust the user verification setting to "discouraged" if they do not want to require users to create or enter PINs. FIDO2 security keys enable passwordless authentication by requiring the physical presence of a USB, NFC, or Bluetooth token, gaining popularity as organizations seek to reduce risks associated with traditional passwords.

Hackers Hit Android Users, Drain Bank Accounts Remotely Through 760 Apps: Report

Cybersecurity experts have identified over 760 malicious applications that exploit Near Field Communication (NFC) technology to target Android devices, compromising sensitive user data and financial information. These apps often disguise themselves as legitimate banking and government services, convincing users to set them as default NFC payment methods. Once installed, they can intercept critical information such as login credentials and card details, which is then transmitted to hackers via Telegram channels. The campaign, which began in April 2024, affects users in countries including Russia, Poland, the Czech Republic, Slovakia, and Brazil, impersonating banks like Santander and VTB. Stolen data is sent to over 70 command-and-control servers managed by automated Telegram bots.
