Google has introduced a new feature for the Play Integrity API that allows banking applications to identify devices that have not received a recent Android security update. This could result in restricted access to sensitive features for users with devices that have not been updated in over a year. The Play Integrity API helps verify the authenticity of software and devices, enhancing security for mobile banking. The update primarily affects users on older Android versions or those without recent security enhancements, as these devices are more vulnerable to cyber threats. Banking applications may limit features like mobile transactions for outdated devices and encourage users to update to maintain access.
