What is rfid

What is RFID?

  • Radio Frequency Identification

  • A small chip or tag that reads radio waves used for identification purposes

  • Does not have to be in line of vision

  • Can be attached to/implanted in products, animals, or even human beings

How does rfid work

How does RFID work?

  • Tags (or chips) consist of two parts:

    1) Antennae

    2) Processor/ storage

  • Receives signal from reader and gives a return signal with ID number

  • Reader sends number to database or server

Types of rfid tags

Types of RFID tags

ACTIVE: Tag signal availability of 100ft.

HIGH signal strength

VERY LOW required signal strength from the reader

EX) Railway cars on a track

SEMI- PASSIVE: Tag signal availability only within field of reader

LOW signal strength

LOW required signal strength from the reader

PASSIVE:Tag signal availability < 10 ft.

VERY LOW signal strength

VERY HIGH signal strength required from reader

EX) Retail Checkout

** Widely used because very cheap to make

Rfid technology a history

RFID Technology: A History

  • WWII (1939-1945):Germans, British, Japanese and Americans all using radar to warn of approaching enemy aircraft.

    • IFF Transponder: Identify Friend or Foe (British)

Rfid technology a history1

RFID Technology: A History

  • 1970s:

    • US government uses RFID to track nuclear materials in transit.

    • US Department of Agriculture partners with research lab to develop a new passive RFID system to track cows and other livestock

Rfid technology a history2

RFID Technology: A History

  • 1990s:RFID transforms into a networking technology (tags like barcodes that are linked to an online database) used to track items in supply chain

Rfid today

RFID Today

  • Present: RFID technology is widely used in product tracking

    • Products can be scanned in mass quantities and tracked from manufacturer to retail to end consumer.

    • Used by many large retailers such as Wal Mart

Its Everywhere!

RFID Today


  • In 1994, the FDA approved implanted RFID chips for humans

  • Used for security and automation of daily tasks

  • An extension of biometrics; in theory it is more secure than eye scans or finger prints

The controversy

The Controversy

Do the advantages of RFID tags and implanted chips, such as security and convenience, outweigh its associated risks, such as breaches in personal privacy?

Advantages of rfid chips

Advantages of RFID chips

Safety and Security

  • Locate/identify missing persons

  • Monitor prisoners, people on

    probation, and predators

Advantages of rfid chips1

Advantages of RFID chips

Easy Access

  • Secure entry to office and residential buildings; other venues

  • Access by authorized personnel only

  • Ease security concerns

Advantages of rfid chips2

Advantages of RFID chips

Medical Emergencies

  • Monitor/Id patients more efficiently

    • Alzheimer’s Disease

  • Quickly access patient medical records

    • Allergies, current medications, family history, etc.

  • Immediate contact with EMS

  • Advantages of rfid chips3

    Advantages of RFID chips

    Advanced Product Tracking

    • Real- time data management

    • Dramatic benefits to manufacturing process

    Advantages of rfid chips4

    Advantages of RFID chips

    Quick Convenience

    • Express payment = more efficient check in/out

      • Grocery Store, Library, Hospital

  • Instant identification

  • Time saver

    Risky business

    Risky Business

    The Downsides and Disadvantages to RFID Technology

    Breach of security

    Breach of Security

    • Illicit use

      • Hacking/viruses

      • Frequencies can be intercepted and manipulated or counterfeited due to novelty of technology

    • Physical theft

      • Threat of physical harm associated with implanted identification information


    Infiltrated RFID systems can mean

    • Identity Theft

    • Unauthorized logging of purchases

    • Tracking/tracing whereabouts of products beyond the retail environment

    • Stalking

    Technological limitations

    Technological Limitations

    • RFID chips readable from ONLY 100ft. away

      • Useless in terms of finding lost persons

    Invasions of privacy

    Invasions of Privacy

    • Human Implantation

      • With the widespread usage of the tags, the whereabouts of people with RFID implants may potentially be tracked

      • Non-democratic governments can gain even more power to deprive people of freedom and privacy

    Invasions of privacy1

    Invasions of Privacy

    • Consumer products

      • “Spy Chips” : Consumer often unaware of tags embedded in products

      • Passive tag design allows for tracking to continue after the purchase has been made

      • Scanning conducted from far away without consumer knowledge

    A Simple Solution?




    Requirements for regulation

    Requirements for Regulation

    • Authorized access to Homeland Security and other security companies

    • Special identification codes to ensure privacy protection

    • Tracking in emergency situations only

    • Enhanced security systems

    Optional removal

    Optional Removal

    • Adults have the right to choose to have RFID chip implanted in them or not.

    • Any children implanted with RFID should have the option to remove it once they turn 18.

    Verichip corp privacy protection system

    VeriChip Corp. Privacy Protection System

    • 16 digit identification number

    • Entered into secure database

    • Information granted to the systems are at the hands of the customer

    Clipped tags another way to regulate

    Clipped Tagsanother way to regulate

    • RFID tag designed to improve consumer privacy protection

    • Consumers can take off a part of the RFID tag

    • Only can be read at short range

    • Still can be used for later purposes



    • Open Business Innovation

    • RFID tags with data freely transferable

    • “Privacy Mode” after the sale

    • Business benefit while protecting consumers’ privacy

      “Without changing our pattern of thought, we will not be able to solve the problems we created with our current patterns of thought”

      -Albert Einstein

    Zombie tags

    Zombie Tags

    • An RFID tag that can be deactivated

    • Once you leave the store, there is a special reader that sends a special deactivating signal to the tag

    • RFID tag "dies."

    Remove the secrecy factor

    Remove the Secrecy Factor

    • Notification on products that contain RFID tags

      • Just like warning labels, ingredient lists, nutritional information

  • Remove the notion that RFID tags are “spy tags”

  • Rule utilitarian decision


    Revolutionize inventory systems/ product tracking in real time


    Helpful in medical and safety emergencies

    Promotes convenience to enhance consumer experience


    Privacy invasion

    Unauthorized purchase logs

    Human tracking

    Extreme circumstances when counterfeited

    Surgery to replace or remove chip

    Identity theft
