6. Automatic PICC Polling

Whenever the reader is connected to the PC, the PICC polling function will start the PICC scanning to determine if a PICC is placed on / removed from the built-antenna.

We can send a command to disable the PICC polling function. The command is sent through the PCSC Escape command interface. To meet the energy saving requirement, special modes are

provided for turning off the antenna field whenever the PICC is inactive, or no PICC is found. The reader will consume less current in power saving mode.

CMD Description Description

Bit 0 Auto PICC Polling 1 = Enable; 0 =Disable

Bit 1 Turn off Antenna Field if no

PICC found

Bit 2 Turn off Antenna Field if the

PICC is inactive.

Bit 3 Activate the PICC when

detected.

• Enable Auto PICC Polling Function = { E0 00 00 23 01 8F}

• Disable Auto PICC Polling Function = { E0 00 00 23 01 8E}

• Read the existing status = { E0 00 00 23 00}; Response = {E1 00 00 00 01 “Status”}

Hints:

1. It is recommended to enable the option “Turn Off Antenna Field if the PICC is inactive”, so that the “Inactive PICC” will not be exposed to the field all the time so as to prevent the PICC from “warming up”.

2. The longer the PICC Poll Interval, the more efficient of energy saving. However, the response time of PICC Polling will become longer.

about 60mA, while the Idle Current Consumption in Non-Power Saving mode is about 130mA. #Idle Current Consumption = PICC is not activated.

3. The reader will activate the ISO14443A-4 mode of the “ISO14443A-4 compliant PICC” automatically. Type B PICC will not be affected by this option.

4. The JCOP30 card comes with two modes: ISO14443A-3 (MIFARE 1K) and ISO14443A-4 modes. The application has to decide which mode should be selected once the PICC is activated.

1 = Enable; 0 =Disable

<0 – 0> = 250 msec

7. PICC Polling for specific PICC Types

The PICC polling function can be configured to detect “ISO14443 Type A PICCs” or “ISO14443 Type B PICCs” or both.

• ISO 14443 Type A PICCs Only = { E0 00 00 20 01 01}

• ISO 14443 Type B PICCs Only = { E0 00 00 20 01 02 }

• ISO 14443 Type A and B PICCs = { E0 00 00 20 01 03} #default setting

• Read the existing status = { E0 00 00 20 00}; Response = {E1 00 00 00 01 “Status”}

Hints:

1. It is recommended to specific the PICC types in the application so as to speed up the card detection process.

8. Auto PPS (Communication Speed Change)

Whenever a PICC is recognized, the reader will try to change the communication speed between the PCD and PICC defined by the Maximum Connection Speed. If the card does not support the proposed connection speed, the reader will try to connect the card with a slower speed setting.

• Set Connection Speed = {E0 00 00 24 02 “Max Tx Speed” “Max Rx Speed”} <Max Tx Speed> & <Current Tx Speed> or <Max Rx Speed> & <Current Rx Speed>

106k bps = 00 212k bps = 01

424k bps = 02 #default setting

848k bps = 03 No Auto PPS = FF

• Read the existing status = {E0 00 00 24 00}; Response = {E1 00 00 00 04 “Max Tx Speed” “Current Tx Speed” “Max Rx Speed” “Current Rx Speed”}

Hints:

1. Normally, the application should know the maximum connection speed of the PICCs being used. #The environment also affects the maximum achievable speed. The reader just uses the proposed communication speed to talk with the PICC. The PICC will become inaccessible if the PICC or environment does not meet the requirement of the proposed communication speed.

2. The reader supports different speed between sending and receiving.

9. Antenna Field ON/OFF

This command is used for turning on/off the antenna field.

• Enable the Antenna Field = {E0 00 00 25 01 01}

• Disable the Antenna Field = {E0 00 00 25 01 00}

• Read the existing status = {E0 00 00 25 00}; Response = {E1 00 00 00 01 “Status”}

Hints:

1. Make sure the Auto PICC Polling is disabled first before turning off the antenna field.

 Advanced Card Systems Ltd. Page 23 of 81

PICC COMMANDS (T=CL EMULATION) FOR MIFARE 1K/4K MEMORY CARDS

2.1 Load Authentication Keys

The “Load Authentication Keys command” will load the authentication keys into the reader. The authentication keys are used to authenticate the particular sector of the Mifare 1K/4K Memory Card. Two kinds of authentication key locations are provided, volatile and non-volatile key locations respectively.

Table 2.1-1a: Load Authentication Keys APDU Format (11 Bytes)

Command

Load Authentication Keys

Key Structure (1 Byte):

0x00 = Key is loaded into the reader volatile memory. 0x20 = Key is loaded into the reader non-volatile memory. Other = Reserved.

Key Number (1 Byte):

0x00 ~ 0x1F = Non-volatile memory for storing keys. The keys are permanently stored in the

0x20 (Session Key) = Volatile memory for storing a temporally key. The key will be disappeared

once the reader is disconnected from the PC. Only 1 volatile key is provided. The volatile key can be used as a session key for different sessions. Default Value = {FF FF FF FF FF FF}

Key (6 Bytes):

<Similarly> // Load a key {FF FF FF FF FF FF} into the volatile memory location 0x20. APDU = {FF 82 00 20 06 FF FF FF FF FF FF}

Hints:

1. Basically, the application should know all the keys being used. It is recommended to store all the

required keys to the non-volatile memory for security reasons. The contents of both volatile and non-volatile memories are not readable by the outside world.

2. The content of the volatile memory “Session Key 0x20” will remain valid until the reader is reset

or power-off. The session key is useful for storing any key value that is changing from time to time. The session key is stored in the “Internal RAM”, while the non-volatile keys are stored in “EEPROM” that is relatively slower than “Internal RAM”.

3. It is not recommended to use the “non-volatile key locations 0x00 ~ 0x1F” to store any

“temporally key value” that will be changed so often. The “non-volatile keys” are supposed to be used for storing any “key value” that will not change frequently. If the “key value” is supposed to be changed from time to time, please store the “key value” to the “volatile key location 0x020”.

2.2.1 Authentication for MIFARE 1K/4K

The “Authentication command” uses the keys stored in the reader to do authentication with the MIFARE 1K/4K card (PICC). Two types of authentication keys are used, TYPE_A and TYPE_B respectively.

Once the authentication is done successfully, there is no need to do the authentication again provided that the blocks to be accessed are belonging to the same sector. Please refer to the MIFARE 1K/4K specification for more details.

#Once the block is authenticated successfully, all the blocks belonging to the same sector are accessible.

Key Type (1 Byte):

0x60 = Key is used as a TYPE A key for authentication. 0x61 = Key is used as a TYPE B key for authentication.

Key Number (1 Byte):

0x00 ~ 0x1F = Non-volatile memory for storing keys. The keys are permanently stored in the

reader and will not be disappeared even the reader is disconnected from the PC. It can store 32 keys into the reader non-volatile memory.

0x20 = Volatile memory for storing keys. The keys will be disappeared when the reader is

disconnected from the PC. Only 1 volatile key is provided. The volatile key can be used as a session key for different sessions.

7.3 Write One Byte Memory Card

To write one byte to the specified address of the inserted card. The byte is written to the card with LSB first, i.e., the bit at card address 0 is regarded as the LSB of byte 0.

Four different WRITE modes are available for this card type, which are distinguished by a flag in the command data field:

a) Write

The byte value specified in the command is written to the specified address. This command can be used for writing personalization data and counter values to the card.

b) Write with carry

The byte value specified in the command is written to the specified address and the command is sent to the card to erase the next lower counter stage. This write mode can therefore only be used for updating the counter value in the card.

c) Write with backup enabled (SLE4436, SLE5536 and SLE6636 only)

The byte value specified in the command is written to the specified address. This command can be used for writing personalization data and counter values to the card. Backup bit is enabled to prevent data loss when card tearing occurs.

d) Write with carry and backup enabled (SLE4436, SLE5536 and SLE6636 only)

With all write modes, the byte at the specified card address is not erased prior to the write operation and, hence, memory bits can only be programmed from '1' to '0'. The backup mode available in the SLE4436 and SLE5536 card can be enabled or disabled in the write operation.

To write data to the specified address of the inserted card. The byte is written to the card with LSB first, i.e., the bit at card address 0 is regarded as the LSB of byte 0.

The byte at the specified card address is not erased prior to the write operation and, hence, memory bits can only be programmed from '1' to '0'.

BASIC PROGRAM FLOW FOR CONTACTLESS APPLICATIONS

Step 0. Start the application. The reader will do the PICC Polling and scan for tags continuously. Once the tag is found and detected, the corresponding ATR will be sent to the PC.

Step 1. Connect the “ACR1281U Interface” with T=1 protocol.

Step 2. Access the PICC by exchanging APDUs.

Step N. Disconnect the “ACR1281U Interface”. Shut down the application.

1. How to access PCSC Compliant Tags (ISO14443-4)?

Basically, all ISO 14443-4 complaint cards (PICCs) would understand the ISO 7816-4 APDUs. The ACR1281U Reader just has to communicate with the ISO 14443-4 complaint cards through exchanging ISO 7816-4 APDUs and Responses. ACR1281U will handle the ISO 14443 Parts 1-4 Protocols internally.

MIFARE 1K, 4K, MINI and Ultralight tags are supported through the T=CL emulation. Just simply treat the MIFARE tags as standard ISO14443-4 tags. For more information, please refer to topic “PICC Commands for MIFARE Classic Memory Tags”

2. How to access DESFIRE Tags (ISO14443-4)?

The DESFIRE supports ISO7816-4 APDU Wrapping and Native modes. Once the DESFire Tag is activated, the first APDU sent to the DESFire Tag will determine the “Command Mode”. If the first APDU is “Native Mode”, the rest of the APDUs must be in “Native Mode” format. Similarly, If the first APDU is “ISO7816-4 APDU Wrapping Mode”, the rest of the APDUs must be in “ISO7816-4 APDU Wrapping Mode” format.

Example 1: DESFIRE ISO7816-4 APDU Wrapping. // To read 8 bytes random number from an ISO 14443-4 Type A PICC (DESFIRE) APDU = {90 0A 00 00 01 00 00}

Class = 0x90; INS = 0x0A (DESFire Instruction); P1 = 0x00; P2 = 0x00 Lc = 0x01; Data In = 0x00; Le = 0x00 (Le = 0x00 for maximum length)

Answer: 1A 29 06 2D 0D C4 00 A6 [$91AF]

# Status Code{91 AF} is defined in DESFIRE specification. Please refer to the DESFIRE specification for more details.

Example 2: DESFIRE Frame Level Chaining (ISO 7816 wrapping mode)

// In this example, the application has to do the “Frame Level Chaining”. // To get the version of the DESFIRE card.

Step 1: Send an APDU {90 60 00 00 00} to get the first frame. INS=0x60 Answer: 04 01 01 00 02 18 05 91 AF [$91AF]

Step 2: Send an APDU {90 AF 00 00 00} to get the second frame. INS=0xAF Answer: 04 01 01 00 06 18 05 91 AF [$91AF]

Step 3: Send an APDU {90 AF 00 00 00} to get the last frame. INS=0xAF Answer: 04 52 5A 19 B2 1B 80 8E 36 54 4D 40 26 04 91 00 [$9100]

Example 3: DESFIRE Native Command.

// We can send Native DESFire Commands to the reader without ISO7816 wrapping if we find that the Native DESFire Commands are more easier to handle.

// To read 8 bytes random number from an ISO 14443-4 Type A PICC (DESFIRE) APDU = {0A 00}

Answer: AF DC E3 4F 26 1D 2D 51 49 [$5149]

In which, the first byte “AF” is the status code returned by the DESFire Card. The Data inside the blanket [$5149]can simply be ignored by the application.

 Advanced Card Systems Ltd. Page 76 of 81

ACR1281U

Example 4: DESFIRE Frame Level Chaining (Native Mode)

// In this example, the application has to do the “Frame Level Chaining”. // To get the version of the DESFIRE card.

Step 1: Send an APDU {60} to get the first frame. INS=0x60 Answer: AF 04 01 01 00 02 18 05[$1805]

Step 2: Send an APDU {AF} to get the second frame. INS=0xAF Answer: AF 04 01 01 00 06 18 05[$1805]

Step 3: Send an APDU {AF} to get the last frame. INS=0xAF Answer: 00 04 52 5A 19 B2 1B 80 8E 36 54 4D 40 26 04[$2604]

Hints: In DESFIRE Native Mode, the status code [90 00] will not be added to the response if the response length is greater than 1. If the response length is less than 2, the status code [90 00] will be added in order to meet the requirement of PCSC. The minimum response length is 2.
