The biometric fingerprint scanner is integrated in the entry door and adds an even more modern looking touch to your Groke Entry Door.

When you swipe your finger over the scanner, its fingerprints are scanned and saved as a unique finger code
Each time you use the scanner, the newly scanned fingerprint is compared with the saved one.

Of all the biometric techniques, finger scan is the most convenient one, due to its cost,user acceptance, security and stage of development. 

Your childrens finger from age 6 onward may also be recognized and the scanners are easy to use for children. 
You need not worry anymore, that your child might lose its keys.
