Unauthorized fingerprint attemps

Hi there, i’m workin on my project it is almost finish… the missing part is when someone attempt unauthorized on my fingerprint sensor(3x) then i want it to send notification to me. And I do not know how it will be possible… will love to read your help… :slight_smile:

There is an email widget and push widget.

The psuedo-code would be like this:

fingerprint_check (Fingerprint)
{ 
if (<unauthorized fingerprint?>)
{ 
Blynk.notify("WARNING: unauthorized person");
} 
} 

Remember: this is only a psuedo-code.
