Only one Tag can be accessed at any one time. • Contactless Interface Carrier = 13.56MHz 4.7. FINGERPRINT SCANNNER AET62 is built around the companion chip and fingerprint sensor. Fingerprint sensor active capacitive sensing provides a much higher immunity to parasitic effects leading to a higher signal-to-noise ratio and the ability to capture a wider range of fingerprints than competing technologies, such as passive capacitive sensing. The matching algorithm will be stored in the Companion chip. The fingerprint matching will be performed on the device. It can provides “Match on device” feature. Typically there are two processes involved in a biometric application: Enrollment: Before the identity of an individual can be verified via his/her fingerprints, it is necessary to capture one or several fingerprint samples. This process is called enrollment. The samples AET62 Design Specification Version 1.0 8-DEC-09 Page 8 of 18 AET62 are referred to as fingerprint templates and can be stored on a broad range of media such as computer storage devices or smartcards. Verification: The verification process requires a user to verify his identity by placing his finger on the fingerprint scanner sensor. The live fingerprint is compared with a stored template using a matching algorithm in order to determine whether they represent the same set of fingerprint. The matching result is then made available to the computer. When using the fingerprint device, the security level is mainly governed by two parameters: False Acceptance Rate (FAR): FAR is the probability that a false sample matches with the original template previously extracted from the subject’s fingerprint images during enrollment. False Rejection Rate (FRR): FRR is the rate at which the system incorrectly rejects a legitimate attempt to verify. AET62 Design Specification Version 1.0 8-DEC-09 Page 9 of 18 AET62 5.0. Commands for Contact and Contactless Interfaces Handling The contactless interface is operating on the top of contact interface. Some Pseudo APDUs are defined for contactless interface. If the reader finds that the APDUs are for contactless interface, the APDUs will be routed to the contactless interface, otherwise, the APDUs will be routed to contact interface. The Contact and Contactless Interfaces are able to be operating at the same time. • The Pseudo APDU “Direct Transmit” is used for sending commands to the contactless interface Command Class INS P1 P2 Lc Data In Direct Transmit 0xFF 0x00 0x00 0x00 Number of Bytes to send PN532_Contactless Command 2. The Pseudo APDU “Get Response” is used for retrieving the responses from the contactless interface. Command Class INS P1 P2 Le Get Response 0xFF 0xC0 0x00 0x00 Number of Bytes to retrieve If the reader finds that the APDU is in the form of “FF 00 00 00 Lc XX XX ..” or “FF C0 00 00 Le”, the APDU will be routed to the contactless interface. Also, one Pseudo APDU “Bi-Color LED and Buzzer Control” is defined for controlling the LED and Buzzer. Command Class INS P1 P2 Lc Data In (4 Bytes) Bi-Color and Buzzer 0xFF LED Control 0x00 0x40 LED 0x04 Blinking Duration Control State Control Similarly, if the reader finds that the APDU is in the form of “FF 00 40 XX 04 XX XX XX XX”, the APDU will be used for setting the LED and Buzzer State. The contact interface must be activated in order to send commands to the contactless or LED interface. AET62 Design Specification Version 1.0 8-DEC-09 Page 10 of 18 AET62 5.1. PSEUDO APDUS IN CONTACTLESS READER PCSC interface is used for exchanging APDUs and Responses between the PC and Tag. The AET62 will handle the required protocol internally. AET62 comes with two primitive commands for this purpose. 5.1.1. Direct Transmit To send an APDU (PN532 and Contactless Commands), and the length of the Response Data will be returned. Table 1.0A: Direct Transmit Command Format (Length of the PN532_Contactless Command + 5 Bytes) Command Class INS P1 P2 Lc Data In Direct Transmit 0xFF 0x00 0x00 0x00 Number of Bytes to send PN532_Contactless Command Lc: Number of Bytes to Send (1 Byte) Maximum 255 bytes Data In: PN532_Contactless Command The data to be sent to the PN532 and Contactless Tag.

AET62 Design Specification Version 1.0 8-DEC-09 Page 14 of 18 AET62 Remark: In general, the Pseudo APDUs “Direct Transmit” and “Get Response” are used in pairs. Once the APDU “Direct Transmit” is sent, the reader will return the length of the response data. Then, the APDU “Get Response” is immediately used to retrieve the actual response data. 6.5. Bi-Color LED and Buzzer Control This APDU is used to control the states of the Bi-Color LED and Buzzer.

Error 63 00 The operation is failed. Table 3.0E: Current LED State (1 Byte) Status Item Description Bit 0 Current Red LED 1 = On; 0 = Off Bit 1 Current Green LED 1 = On; 0 = Off Bits 2 – 7 Reserved 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%. #Duty Cycle = T1 / (T1 + T2). 5. To control the buzzer only, just set the P2 “LED State Control” to zero. 6. The make the buzzer operating, the “number of repetition” must greater than zero. 7. To control the LED only, just set the parameter “Link to Buzzer” to zero.
