1 What is IC card?
IC means Integrated Circuit,IC card also called smart card,intelligent card,microcircuit card or microchip card.It is composed of card body and chip with antenna.

2 Where IC card used?
IC card are used in Bank,Transportation,Telecom,Social Security,secure access and many other public utilities.

3 How to devide IC card?
1) IC card devided by chips
Memory card Security Card and CPU card(normal card or Java card),details:
Memory card:only EEPROM, with non-programmable logic
Security card:EEPROM + logistic security circuit
CPU card:ROM + RAM + EEPROM + micro processor + COS (Chip operating system)
Java card: CPU card base on Java language.
Because there are many chips producer and the standard still not united,it gives puzzle to the application developer of IC card.Java card and language resolve this matter.
2) IC card devided by the reading and writing mode:
Contact card and non-contact IC card, combined-type IC card of dual purpose.details
Contact card: the card get energy from reader and exchange data with reader/writer by the point (can see) outside the card
Non-contact IC card: contactless card, radio frequency card,RF card,the card get energy and exchange data with reader/writer by radio frequecy
Combined-type IC card of dual purpose: one card using both contact and non-contact technology

4 Nature of information secutiy compared of some cards:
Barcode card<magnetic strip card<contact memory card<security card<cpu card compare details of card

contact ic card

5 Comparing with the contact-type IC card, the non-contact IC card has the following advantage:
5.1 Dependability is high
With read writing device there is no machinery to keep in touch contact-type IC card non.Have avoided various kinds of troubles that are produced because of contacting and studying in writing. For example: Because rude to insert the card, does not nip the other thing to insert in , the dust or the greasy dirt cause and contact the bad trouble that causes.In addition, the non-contact IC card surface has not uncovered the chip.Needn’t be afraid the chip comes off.The static is punctured , crooked question of damaging etc. Since benefit cards to print , improve the use dependability of the card.
5.2 Easy to operate
Because does not contact the communication.Reading the writing device can operate the card within the range of 10CM.So needn’t insert and set aside the card , help users use very much.There is no directionality when being used in the non- contact-type card.The card can skim over and read the writing device surface in the wanton direction , can already finish operating. This has improved the speed used each time greatly.
5.3 Defend the conflict
Defend the conflict mechanism fast in the non- contact-type card.Can prevent interfering the data between cards.So read person who write can deal with many pieces of contact-type IC card non- ” at the same time “.Improve the running side by side used, improve the speed of system work virtually.
5.4 Can be suitable for many kinds of application
The sequence number of the non- contact-type card is only.Before the products are dispatched from the factory already this sequence number solidification manufacturer. Can’t alter again.The non- contact-type card is with adopting the two-way mechanism of proving while reading the writing devices.Legitimacy of the IC card that namely read the writing device to prove.At the same time the IC card proves that the legitimacy of the writing device is studied in too.Non- contact-type to block before not dealing with wanting and reading writing device not to carry on the mutual authentication three times.And all data are encrypted in the course of communication.In addition card all sector have own operation password and visit terms.The memory structure characteristic of the contact-type card makes its one calorie multi-purpose.Can apply to different systems , users can establish different passwords and visit condition according to different application.
5.5 It is of good performance to encrypted

6 What is main standard of IC card
ISO7816
ISO10536
ISO14443

7 How to devide non-contact IC card?
7.1 Non-contact IC card devided by frequency used
1)125-134 Khz Low Frequency (LF) sample: EM4100 ID card, T5557 card
2)13.56 Mhz High Frequency (HF)
sample:MF1 card (or Mifare one,Mifare 1,it is same),I-Code-II card
3)433–869–915 Mhz Ultra High Freqency(UHF)
sample: UCODE card
4)2.45–5.8Ghz Microwave card
sample:EM4122
7.2 non-contact IC card devided by length from card to reader/writer
Close distance,Long distance
by Standard used
ISO/IEC14443 TYPE A MIFARE standard card
ISO/IEC14443 TYPE B standard card

8 What is ID card?
ID card also called RFID card.It is one kind of non-contact IC card with less memory and usually do not write (or writeable area very small size) after it is made.It has one number shows identity
book: RFID for Dummy

9 What chips is mostly used in IC card?
