Micro SD card not detecting

I was purchasing last year diwali time SanDisk 16GB SD card now its not working within years is not detecting with my computer or smartphone please help me…

if it is not detected on multiple device where it worked before it is likely bad and would need to be replaced. contact sandisk support to check the warranty status.
