Fingerprint sensors are considered insecure due to the relative ease with which 
they can be bypassed, either create a mould from a sample fingerprint, or more 
morbidly just chop off the finger. That's why when you restart the iPhone you 
can't use touchID to unlock it first time.

Barclays are using finger scanners which use infrared light to map the 
structure of veins, it's just as secure as a fingerprint and only works on live 
tissue.

PIN codes can't be guessed or faked unless the user is lax with security ie 
using the same PIN for everything or writing it down.

Samsung have had a fingerprint scanner since the Galaxy S6, or possibly the S5. 
Motorola used to use one years ago but it was horribly unreliable.

Come on! Pass codes are common but they aren't secure and certainly not a key 
security mechanism for Apple. Touch ID is.
I wouldn't mind a very small wager that it will with the Mac before too long. 

And didn't I read somewhere that Samsung are copying the idea in their next 
smartphone series?
