How do I know if RFID is being used?

Items that are tagged with chips that carry the EPC are marked with the EPC symbol. Usually, the symbol  is on the removable packaging or integrated into a product label. The logo means that the manufacturer of the product has agreed voluntarily to disclose the use of RFID. But more than that, the EPC symbol means that the retailer has agreed to adhere to voluntary guidelines relating to consumer privacy. According to these guidelines, consumers should be given:

• Notice if EPC technology is being used
• Choice of different options for discarding or removing the EPC tag after purchase
• Education about EPC technology and its uses

In the case of other uses of RFID without EPC, customers can be informed that it is in use by reading a sign in a store or checking product labels, contracts or user agreements.
