Definitions

  • the present disclosure concerns a system and method for selecting a single RFID tag from a group of tags which are all in range of an RFID reader without interference from the other tags.
  • the original concept of the present disclosure is for a "Smart Wallet” device. Consumers buy smart watches for its utility and accessibility even though it's basically a phone for the wrist. Similarly, the selling point of a smart wallet is its added physical storage compared to a phone. If you have a thick stack of cards, you still need to bring something to store it in, like a wallet. Thus, making your wallet “smart” could be enticing for consumers.
  • RFID cards are very convenient for users, but if a user has multiple RFID tags in their storage container, they have to ensure that only their desired tag gets in range of the tag reader. For example, in the case of NFC tags, the user has to physically take out their desired tag from their wallet before tapping it onto the tag reader. If they tap their wallet onto the tag reader, the reader might read the wrong card, or it might not read any card at all. This could present a potential security risk since a store might be able to read the user's sensitive cards (e.g. bank ATM cards).
  • NFC tags the user has to physically take out their desired tag from their wallet before tapping it onto the tag reader. If they tap their wallet onto the tag reader, the reader might read the wrong card, or it might not read any card at all. This could present a potential security risk since a store might be able to read the user's sensitive cards (e.g. bank ATM cards).
  • the tag reader is capable of separating the signals from multiple tags, it could still be a problem if a user has multiple tags that the tag reader may detect. For example, if a user has two or more credit/debit cards, then even if a payment terminal tag reader may separate the other cards that the user owns, it still may not distinguish which of the cards the user wishes to use. Most cards today are NFC capable, like transportation cards, payment cards, and bank cards, leading to more users currently experiencing this problem.
  • An embodiment of the disclosure is to provide a method of selecting a single RFID tag from a group of tags which are all in range of an RFID reader - without interference from the other tags.
