Well depends how many 555's you'd have to sell to get enough money for an iris biometric module?
Think out of the box :-)

Yes, wonderfully versatile chip can do all sorts of weird and wonderful
things.
So how many would you need for TI's April 1st application suggestion of
iris biometrics?

Sure, I designed an ultrasonic distance meter with one in the eighties
to measure water height in wells.
555 and some CMOS counters.

Although it's not a biometric device, earlier this year, a 555 power
bank keepalive was designed and built by me:
<https://crcomp.net/mp3mod/index.php>
The gadget is used every single day and it works perfectly. The power
bank lasts about a month between charges. The gadget's used exclusively
to listen to audio books on dog walks and spins:

Been a long time since I last looked at a 555 datasheet but it seems
they are more capable than I ever imagined. Now that many processors are
on 52 week lead times we can squeeze more from of ol' faithfulls?

2 Applications
• Fingerprint Biometrics
• Iris Biometrics
• RFID Reader
Do not scrimp by using the vanilla LM555 which lacks the magic
functionality :)
