Communication Protocol Physical layer This layer defines the physical and electrical characteristics of data transfer Data link layer This layer defines the data transfer method and the error detection scheme. Application layer This layer defines the specifications and functions of data strings to be handled as commands.

File System Block Smallest unit of File System Data is divided into blocks of 16 bytes. RC-S885 (154 blocks are available)

File System Service All access to the Block is performed by using service Each service regulate a range of block Service is called using Service code Service là cái quan trọng, service code có tác dụng định danh từng loại service

File System Service Types Random Service Cyclic Service Purse Service This is the general-purpose Service. This Service provides access to Block and can read and write data by specifying any Block. Cyclic Service This is the Service that assumes the role of log management. This Service provides access to Block and deletes the oldest data every time new data is written. Purse Service This Service provides access to Block and automatically performs numerical operations on specific data in the Block - Dung de luu thong tin cu, tranh tinh trang thong tin cu bi ghi de len thong tin moi

File System Service Service code Example: Read / Write Access: Service Code of Random Service that requires authentication (0001 0010 1100 1000)b = 12c8h - - 6 bit cuoi qui dinh loai service

File System Service Service code

File System Area It’s possible that a area contain some areas Area 0 is the root area (area code = 0000h) Each area is distinguished by area code (2bytes)

File System System Reader/Writer only work for one system at a time Each system is distinguished by system code (2 bytes) Switching between Systems using Idm Include several Area

Commands Polling command Request Service Request Response Read Without Encryption Write Without Encryption Request System Code Authentication1 Authentication2 Read Write

Commands Polling command Use this command to acquire and identify a card Response Request

Commands Request Service Request Response Read Without Encryption Use this command to check for the existence of Area / Service specified by Area Code / Service Code Request Response Use this command to check whether a card exists Read Without Encryption Use this command to read Block Data from a Service that requires no authentication.

Commands Write Without Encryption Request System Code Authentication 1 Use this command to write Block Data to a Service that requires no authentication. Request System Code Use this command to acquire System Code of the System located on a card. If a card is divided into multiple System, this command acquires System Code of all the System existing in the card. Authentication 1 Use this command to authenticate cards

Commands Authentication 2 Read Write Use this command to allow a card to authenticate a Reader/Writer. Read Use this command to read Block Data from a Service that requires authentication. Write Use this command to write Block Data to a Service that requires authentication.
