!!HELP DISNEYLAND FINGERPRINT & MULTI DAY TIX!!!!!! HELP?

i know that disney world and disneyland in tokyo both use fingerprints in order to track the original owner of the tickets so they cannot be transferred. My question is do they use this technology at disneyland anaheim as well? if so does anyone know generally when they scan your fingerprints? is it on the first day of the ticket or 2nd or 3rd etc? sometimes they require you to sign the ticket also at disneyland what day of the ticket is that generally done on? any help is greatly appreciated. thank you!
