Pseudo APDUs for Contactless Interface and Peripherals Control ACR122L-USB-ACS 6.0. PICC Interface Description 6.1. ATR Generation If the reader detects a PICC, an ATR will be sent to the PCSC driver for identifying the PICC. 1.1 ATR format for ISO 14443 Part 3 PICCs. Byte Value Designation Description (Hex) 0 3B Initial Header 1 8N T0 Higher nibble 8 means: no TA1, TB1, TC1 only TD1 is following.

ACR122L-USB-ACS Hint: Use the APDU “FF CA 01 00 00” to distinguish the ISO14443A-4 and ISO14443B-4 PICCs, and retrieve the full ATS if available. ISO14443A-3 or ISO14443B-3/4 PICCs do have ATS returned. APDU Command = FF CA 01 00 00 APDU Response = 06 75 77 81 02 80 90 00 ATS = {06 75 77 81 02 80} E.g 2. ATR for ST19XRC8E = { 3B 8C 80 01 50 12 23 45 56 12 53 54 4E 33 81 C3 55} // 12 bytes of ATQB, No CRC-B ATQB = {50 12 23 45 56 12 53 54 4E 33 81 C3} 6.2.

Checksum Error 63 27 The checksum of the Response is wrong. 6.2.2. Direct Transmit via ScardControl Command = {E0 00 00 24 XX “PN532_TAG Command”} Response = {E1 00 00 00 YY “PN532_TAG Response”} XX = Length of the “PN532_TAG Command” YY= Length of the “PN532_TAG Response” 6.3.
0 = No ACR122L-USB-ACS change Bit 4 Initial LED_1 Blinking State 1 = On; 0 = Off Bit 5 Initial LED_0 Blinking State 1 = On; 0 = Off Bit 6 LED_1 Blinking Mask 1 = Blink 0 = Not Blink Bit 7 LED_0 Blinking Mask 1 = Blink 0 = Not Blink Data In: Blinking Duration Control Table 2.
ACR122L-USB-ACS Remark: 1. The LED State operation will be performed after the LED Blinking operation is completed. 2. The LED will not be changed if the corresponding LED Mask is not enabled. 3. The LED will not be blinking if the corresponding LED Blinking Mask is not enabled. Also, the number of repetition must be greater than zero. 4. T1 and T2 duration parameters are used for controlling the duty cycle of LED blinking and Buzzer Turn-On duration. For example, if T1=1 and T2=1, the duty cycle = 50%.
Example 1: To read the existing LED State. ACR122L-USB-ACS // Assume both LED_0 and LED_1 are OFF initially // // Not link to the buzzer // APDU = “FF 00 40 00 04 00 00 00 00” Response = “90 00”. LED_0 and LED_1 LEDs are OFF. Example 2: To turn on LED_0 and LED_1 // Assume both LED_0 and LED_1 are OFF initially // // Not link to the buzzer // APDU = “FF 00 40 0F 04 00 00 00 00” Response = “90 03”.
ACR122L-USB-ACS Example 4: To turn on the LED_1 for 2 sec. After that, resume to the initial state // Assume the LED_1 is initially OFF, while the LED_0 is initially ON. // // The LED_1 and buzzer will turn on during the T1 duration, while the LED_0 will turn off during the T1 duration.
ACR122L-USB-ACS 1Hz = 1000ms Time Interval = 500ms ON + 500 ms OFF T1 Duration = 500ms = 0x05 T2 Duration = 500ms = 0x05 Number of repetition = 0x03 Link to Buzzer = 0x01 APDU = “FF 00 40 50 04 05 05 03 01” Response = “90 02” Example 6: To blink the LED_1 and LED_0 of 1Hz for 3 times // Assume both the LED_0 and LED_1 are initially OFF.
// The buzzer will turn on during the T1 duration// ACR122L-USB-ACS LED_1 On LED_1 Off T1 500ms = T2 500ms = LED_0 On LED_0 Off Buzzer On Buzzer Off 1Hz = 1000ms Time Interval = 500ms ON + 500 ms OFF T1 Duration = 500ms = 0x05 T2 Duration = 500ms = 0x05 Number of repetition = 0x03 Link to Buzzer = 0x01 APDU = “FF 00 40 D0 04 05 05 03 01” Response = “90 00”

7.0. Basic Program Flow for Contactless Applications ACR122L-USB-ACS 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 “ACR122L PICC Interface” with T=1 protocol. Step 2. Access the PICC by exchanging APDUs. .. Step N. Disconnect the “ACR122L PICC Interface”. Shut down the application.
7.1. How to access PCSC Compliant Tags (ISO14443-4)? Basically, all ISO 14443-4 complaint cards (PICCs) would understand the ISO 7816-4 APDUs. The ACR122L-USB-ACS ACR122L-USB Reader just has to communicate with the ISO 14443-4 complaint cards through exchanging ISO 7816-4 APDUs and Responses. ACR122L-USB 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.
Typical sequence may be: - Present the Tag and Connect the PICC Interface - Read / Update the memory of the tag Step 1) Connect the Tag The ATR of the tag is 3B 8C 80 01 50 57 26 34 D9 1C 2D 94 11 F7 71 85 76 In which, The ATQB = 50 57 26 34 D9 1C 2D 94 11 F7 71 85. It is an ISO14443-4 Type B tag. Step 2) Send an APDU, Get Challenge. << 00 84 00 00 08 >> 44 70 3D A2 6C DA 43 D5 [90 00] Hint: For ISO14443-4 Type A tags, the ATS can be obtained by using the APDU “FF CA 01 00 00” Website: www.acs.com.
For Example: ISO7816-4 APDU // To read 8 bytes from an ISO 14443-4 TypeA PICC APDU ={80 B2 80 00 08} Class = 0x80 INS = 0xB2 P1 = 0x80 P2 = 0x00 Lc = None Data In = None Le = 0x08 Answer: 01 02 03 04 05 06 07 08 [90 00] Website: www.acs.com.hk Email: info@acs.com.
7.2. 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.

Tip: To read all the memory content of the tag ACR122L-USB-ACS << 00 >> 11 49 18 26 .. 00 [90 00] Step 3) Update the memory address 08(Block 1: Byte-0)with the data FF << 53 08 FF >> FF [90 00] In which, Response Data = FF Topaz Memory Map. Memory Address = Block No * 8 + Byte No e.g. Memory Address 08 (hex) = 1 x 8 + 0 = Block 1: Byte-0 = Data0 e.g. Memory Address 10 (hex) = 2 x 8 + 0 = Block 2: Byte-0 = Data8 #please refer to the Jewel and Topaz specification for more detailed information.
ACR122L-USB-ACS 8.0. Basic Program Flow for SAM 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 “ACR122L SAM Interface N( N = 0, 1, 2 )” with T=0 or T=1protocol. Step 2. Access the PICC by exchanging APDUs. .. Step N. Disconnect the “ACR122L SAM Interface N( N = 0, 1, 2 )”. Shut down the application.
