An anti-theft system that has a first component that is an attractive and light-weight smart charm that uses an accessory attachment means to attach to a wearable accessory such as a bracelet or necklace, an item of clothing, or user. The system has a second component that is an object monitor for attaching or combining with a mobile object, such as a wallet or purse.
