** How Can You Tell If Your Credit Cards Have RFID Chips? **

As you may know the HuMn Wallet protects against RFID skimming, but what is
RFID? It stands for Radio Frequency Identification. It’s important to
know what it is, but does it apply to you?

RFID chips are found in many items we use daily, not just credit cards.
They are used in cards that open electronic locks, cards that let you drive
through a toll booth without stopping, the remote that opens your car door,
workplace ID that unlocks the office door, and even passports.

Credit cards are now becoming more equipped with these chips.  Standard
credit cards store account information on the magnetic stripe used for
swiping but credit cards that use RFID technology store data inside a
“smart chip” within the plastic. The chip uses electromagnetic waves to
transmit account information to a reader. RFID chips do not require contact
to transfer information. They are used to create better convenience for the
user and the merchant.

*Radio-frequency identification* (*RFID*) is the wireless non-contact use
of radio-frequency electromagnetic fields to transfer data, for the
purposes of automatically identifying and tracking tags attached to
objects. The tags contain electronically stored information. Some tags are
powered by and read at short ranges (a few meters) via magnetic fields
(electromagnetic induction), and then act as a passive transponder to emit
microwaves or UHF radio waves (i.e., electromagnetic radiation at high
frequencies). Others use a local power source such as a battery, and may
operate at hundreds of meters. Unlike a bar code, the tag does not
necessarily need to be within line of sight of the reader, and may be
embedded in the tracked object.

RFID tags are used in many industries. An RFID tag attached to an
automobile during production can be used to track its progress through the
assembly line. Pharmaceuticals can be tracked through warehouses. Livestock
and pets may have tags injected, allowing positive identification of the
animal. On off-shore oil and gas platforms, RFID tags are worn by personnel
as a safety measure, allowing them to be located 24 hours a day and to be
quickly found in emergencies.^[1]

Since RFID tags can be attached to clothing, possessions, or even implanted
within people, the possibility of reading personally-linked information
without consent has raised privacy concerns.
