system block of AET62 is shown as follow:
USB
Computer
Interface
The USB Hub Controller is the communication interface between the PC and the host controller and
fingerprint sensor via USB port connection. The companion chip get the fingerprint image form the
Strip sensor and contains the fingerprint template extraction and matching algorithms. The template
matching can be performed in device. The AET62 is powered from USB port without external power
supply.

• The estimated size = 50mm x 40mm.
• The loop inductance should be around ~ 1.6uH to 2.5uH
• Operating Distance for different Tags ~ 40mm to 50mm
• No anti-collision. 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
18
Page 9 of
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.

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

Transmit
2. The Pseudo APDU “Get Response” is used for retrieving the responses from the contactless
interface.

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

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.

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.

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.

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.
