a lock body,
a shackle with a long leg and a short leg, wherein the long leg of the shackle never comes out of the lock, and
a fingerprint panel wherein the fingerprint panel and an associated memory, battery, and processor are configured to associate a fingerprint of a user to one of a plurality of lock control levels, said associated fingerprint considered a registered fingerprint, wherein each lock control level allows an associated lock control level user to unlock said lock, the lock including a driving electronic circuit, electro-mechanical control motor, and a latch, that are configured to unlock the lock if a registered fingerprint is placed on said fingerprint panel, and
