CompTIA A+ 220-1102 Practice Question

The most likely cause of the issue described is that the feature for wireless data exchange and payments is disabled in the device settings. Sometimes, users may unintentionally disable this feature or software updates may revert settings to a default state where it is turned off. Re-enabling this in the settings should resolve the problem. Checking for physical obstructions would generally not solve issues related to touchless technology unless there is noticeable damage that might impede its function, which wasn't specified in the scenario. Inspecting the device for malware is important for comprehensive troubleshooting, but it wouldn't directly affect this functionality unless specific malware was designed to interact with wireless communication features. Checking for OS updates is always a good practice, but it is less likely to be the direct cause of an immediate stop in such functionalities if updates were not recently installed.
