NTT Develops first Multi-application Smart Card in compliance to GlobalPlatformTMV2.1 specifications

-- Dramatically increases application and data storage to enable true multi-application usage --


Nippon Telegraph and Telephone Corporation (NTT; Head Office: Chiyoda-ku, Tokyo; President: Norio Wada) has developed first smart card that is in compliance to GlobalPlatformTM*1 V2.1 specifications - which are recognized as the de facto standard for multi-application smart card*2 platforms in financial and other fields - and that offers the world's largest memory capacity (1 MB) for this type of card.
Because this card offers far more memory than existing GlobalPlatformTM cards, it enables installation of several times more application programs, as well as storage of huge volumes of data, such as fingerprints and other biometric information required for biometrics authentication*3.
This card also offers a number of features not available in existing GlobalPlatformTM cards, such as contactless interfaces*4 and execution functions for programs created in C language*5. This will enable GlobalPlatformTM cards to be used in fields that emphasize speed and contactless operation, such as electronic tickets, electronic money, and building entry management cards.
With these functions, NTT has created a true multi-application smart card that can be used for a wide range of purposes even outside the financial field (see Figure).


Background to development

NTT has been developing multi-purpose, multi-application smart cards for several years, and has been a member of GlobalPlatformTM since the consortium was first established.
The memory capacity for storing downloaded application programs in earlier GlobalPlatformTM cards was between 16 and 64 KB, so no more than five or six applications could be downloaded. These cards did not have enough memory for applications in non-financial fields to be installed, or to allow the card to be used in biometric authentication. Most of the cards only have contact-type interfaces*6, and in many cases the processing speed was limited, so application programs could only be created in Java language*7. This meant that it was difficult to use these cards in fields where contactless interfaces and high-speed processing were emphasized, as in the case of electronic tickets, electronic money, and building entry management cards.


Features of this smart card

(1) Obtain recognition of the compliace to GlobalPlatformTMV2.1 specifications for the first time in the world.
The compliance to GlobalPlatformTMV2.1 specificatons - which are recognized as the de facto standard for multi-application smart card platforms - was recognized for the first time in the world.

(2) Offers a memory capacity of 1 MB, the highest level of any GlobalPlatformTM card in the world.
By using the large-capacity smart card developed by NTT, this card achieves a memory capacity of 1 MB, which represents the highest level of any card of its kind in the world. More than 300 KB of memory is available for storage of downloaded application programs, making it possible to load five or six times more application programs than in the past. The card can also store over 100 KB of biometrics authentication data at the same time.

(3) Enables use of contactless interfaces, dramatically improving operability for electronic money, building entry management cards, and other applications
This new card is compatible with not only ISO7816 contact-type but also ISO14443 Type B contactless interfaces. Processing can be completed by simply approaching the smart card reader/writer, so the operability of GlobalPlatformTM cards used for electronic money or building entry management improves dramatically. There is no need to distinguish between application programs that use contact or contactless interfaces, which means that existing application programs using contact interfaces can be used with contactless interfaces almost entirely without modification.

(4) Programs in C language can be executed, expanding the range of applications to include electronic tickets and other card types that demand high-speed operations
In addition to Java language, which requires a virtual machine, some application programs can be created using C language, which generates formats that can be executed directly by CPU commands. These application programs also offer a function that enables them to be started up first when the card is activated. In this way, NTT has achieved practical processing performance even for application programs that emphasize high-speed operations, as in the case of electronic tickets.


Future developments

From now on, in order to develop this smart card to each field, the smart card platform that offers card application programs download - which is the feature of GlobalPlatformTM specification etc. - is improved. For some time now, NTT has been developing the smart card information sharing platform "NICE," *8 which will enable application programs to be downloaded safely to smart cards via the Internet and other networks whenever they are needed. In the future, NICE will enable downloading of application programs to GlobalPlatformTMcards in order to promote expansion into various fields.


Glossary

*1 GlobalPlatformTM
A consortium established in 1999 by various cross industry companies and organizations. This consortium creates GlobalPlatformTM specifications that define, for example, architectures for multi-application smart cards targeting mainly the financial field, and command specifications for downloading application programs.

*2 Multi-application smart card
A smart card that allows several applications to be installed in a single card, thus increasing convenience by enabling one card to be used for multiple services.

*3 Biometrics authentications
A method of identifying an individual based on unique physical characteristics, such as fingerprints, voice, iris pattern, or voice.

*4 Contactless interfaces
A method in which a coil (antenna) is embedded within the smart card, and data is transmitted without having the smart card come in contact with the smart card reader.

*5 C language
A compiler-type programming language that enables structured programming. Programs described in C language are converted by a C compiler into code that can be directly executed by the CPU (native code), making C language more suitable for high-speed processing than programming languages that are converted into an intermediate code.

*6 Contact-type interfaces
A method in which the smart card and the smart card reader are connected by a six-pin or eight-pin external terminal, and data is transmitted through this connection.

*7 Java language
Java is an intermediate code executed, object oriented programming language. Programs described in Java language are converted into an intermediate code that does not exist in the executing CPU, and are executed on a Java Virtual Machine (Java VM). For this reason, programs described in Java can be executed even in differing operating environments, as long as the environment running the program is a Java VM.

*8 NICE
Network-based IC Card (Smart card) Environment. NICE is the multi-application smart card information-sharing platform developed by NTT. By using NICE, whenever the user needs it, the user can safely download the application program on a smart card via a network, or can safely delete the downloaded application program.
