RFID is an advanced technique for attaching information to objects of all kinds, and ICs such as the ST25DV series can help you to implement this technology.

Those of us who have no experience with manufacturing environments or shipping warehouses probably cannot imagine the immense effort required to “keep track of everything,” for lack of a more sophisticated description. I’m assuming that bar codes and other techniques are still widely used, but RFID (radio-frequency identification) offers significant advantages.

So what exactly is RFID? It’s the same general idea as a bar code: We want to attach information to a physical object. Bar codes accomplish this using black-and-white patterns that are optically scanned and interpreted as data. RFID accomplishes this via tags that are attached to or embedded within an object; the tag contains digital data that can be accessed via electromagnetic radiation.
