Features

[Inherited features]

Highest level of security for contactless smartcard IC chips

The IC chip supports the AES encryption method and provides high security. With its state-of-the-art tamper-resistant technology, it has acquired the very high assurance level of EAL6+, in accordance with ISO/IEC 15408 Common Criteria certification, an international standard for security (Certificate issue date:2021/10/26, Certificate expiry date:2026/10/26). The IC chip also complies with Public Transportation IC Card Protection Profile (PTPP).

Multi-application platform with higher performance and reliability

Higher transaction speed is achieved for every type of card application, such as transportation ticket and e-payment. In addition, the IC chip achieves lower power consumption than the current FeliCa IC chips.

Communication with NFC Forum-compatible readers

The chip complies with Type 3 Tag functionality defined by the NFC Forum. Therefore, a card with the chip can communicate with NFC-compatible smartphones and readers.

[New features]

Additional security options to meet market needs

In addition to the encryption and integrity protection of communication data in the current secure communication function, a security option that supports only integrity protection of communication data has been added. This extends the choice of cost-balanced system solutions for use cases where higher priority is given to high-speed transactions, while meeting the required security needs.

Extended Overlap Service

This feature allows different service providers to share additional services, while making the most of existing systems.

Value-Limited Purse Service

Value-Limited Purse Service enables the purse data to be set as a negative numerical value, and enables "Upper Limit Value" and "Lower Limit Value" to be specified.
