Speed,
convenience and safety are the main properties for IC card to be popular
today. The smart cards which contain CPU and EEPROM can save 10 to
10 K bytes with very high security. IC card not only have the memory
to save the data but also have ability to execute the programs on
card. It can be widely used in the ID cards, credit cards, e-purse,
coupons, digital signature and so on.
Memory card is a chip card without any CPU and it can store the data
and implement the simple logic and mathematical algorithm with lower
level security than CPU card. The memory card can play the good role
in telephone card and transportation cards.
Smart card is a chip card with CPU and can provide the functions of
encryption/decryption and can perform the complex algorithms with
high security level. The smart cards are very popular in the Europe,
especially in e-pay system, transportation system, phone system, super
market payment system, parking and gas station payment system.
Since the specifications of the smart card are not coherent with each
other. Then Euro pay, Master cards and Visa cards have work out the
EMV specifications for speedy the development of E-Purse system.
In 1993, the financial information center gathered part of the local
banks in Taiwan to develop the Local banking smart card processing
the functions of withdrew, transaction, IC phone card and also offer
the functions of e-purse. The demand of the SIMs is rapidly increase
due to the mobile phone to be popular in the world in 1998. STK functions
extend the Smart card market in searching on line, shopping, ordering,
transaction and games.
The Master and VISA decide to migrate the magnetic strip card to chip
cards in order to decrease the false rate of the credit cards such
as VSDC (Visa Smart/Debit Card) cards for VISA and M/Chip cards for
Master. Since the digital signature will also be accepted broadly
and also the safety, speedy and convenient properties of the smart
card, sure it will be apply to all the diversity directs in different
regions.
