A better solution for bike theft and recovery would be for manufacturers to epoxy an RFID tag into every frame they produce. RFID tags do not require a battery and there so small they are commonly injected under the skin of pets and even people. A manufacturer could easily embed it so it would be extremely difficult to find and remove and if it were removed that immediately signals anyone trying to read the RFID that it's stolen. Carbon Fiber frames would allow the RFID to be molded into the frame so the only way to remove it would be destruction of the frame. RFID readers are becoming common at the doors of retailers. They read every RFID tag entering or exiting the store. It's become common for expensive clothing manufacturers to embed RFID tags in every article of clothing they sell. If a shop lifter steals an RFID tagged item and gets it out of the store without paying for it the reader will sound an alarm and log the item as stolen. If the item is ever picked up by any reader it's flagged as stolen so the person with that item can be picked up and prosecuted for receiving stolen goods at the very least. Most stolen bicycles will be taken to a bike shop by the thief in an attempt to sell it. As soon as the thief enters a bike shop or any retailer with an RFID system the shop or retailer will know the bike is stolen, who the real owner of the bike is, and can have the thief arrested and the bike returned to it's rightful owner.
