Abstract
Many objects these days are tagged electronically. When leaving a store, it’s possible that an alarm will go off if you leave with an item that still has a tag on it. A purchase can be made by waving a tag over a credit card machine. These technologies use radio-frequency identification (RFID) to tag and track items based on a chip placed on an item and a device that can read it. You can use this technology to trigger reactions in your LEGO creations, like the crystal ball you are going to build in this chapter.
