The Yale 4109 can register up to 20 fingerprints, and you can also use a passcode to unlock. 

If your door has a long metal handle bar like the one in the picture above, you can take the Yale 4109R, which doesn't have a lever handle. Instead, it is a Roller Mortise.

 

Installation is very fast for this lock most of the time, as compared to the Samsung 718.

 

 

 

If you are staying in a HDB, and have a metal gate, you can also choose to install the Yale 4110 too. So you can conveniently use 1 fingerprint to unlock both the metal gate and main door.
