In general, contact-type cards that read and write data are categorized as IC
cards. Typical examples include cash cards and credit cards from financial
institutions. They are widely used in “financial information systems.”

Credit card
A “credit card” is a card issued on the
basis of an agreement between a consumer and a credit card company. The
con sumer can buy products or receive
services by using the card within the
limitations of its terms (such as expiration date and credit limit).
Payment of charges incurred by using
the card is deferred, and the user pays
after receiving a bill from the credit card
company.

“Contact type” is a method for reading/
writing data to or from an IC card by inserting the card into a device.

(3)RFID
“RFID” is the use of tiny “wireless chips” for identifying and managing
people and things.
Wireless chips are easily attached to people or materials because they can
be incorporated into items such as self-adhesive labels, envelopes, key
holders, or wristbands. Furthermore, an important feature is that they can
simultaneously identify multiple people or materials. Therefore, wireless
chips are used in a variety of situations such as management of comings
and goings of people using wireless chips in key holders, or “traceability
systems” that manage distribution histories for vegetables or meat using
wireless chips in the form of self-adhesive labels. A wireless chips may
also be called an “IC tag” or “wireless IC.”
The communication range between a wireless chip and a reader is from
several centimeters to approximately two meters, and an antenna provides
power to the wireless chip.
Also, building an antenna into an IC card makes wireless reading and writing possible. Therefore, contactless IC cards are categorized as technology
based on RFID. Typical examples are electronic money, tickets for public
transportation, driver’s licenses, and citizen identification cards.

Traceability system
A “traceability system” is a system for
ensuring food safety, which clarifies
production and distribution processes
by tracing them back from the point of
consumption to the point of production.
