4.3. Bi-Color LED
•
User-controllable Bi-color LED. Red and Green Color.
•
The Green Color LED will be blinking if the “Card Interface” is not connected.
•
The Green Color LED will be turned on if the “Card Interface” is connected.
•
The Green Color LED will be flashing if the “Card Interface” is operating.
•
The Red Color LED is controlled by the application only.
4.4. Buzzer (optional)
•
User-controllable buzzer.
•
The default Buzzer State is OFF
4.5. SAM Interface (optional)
•
One SAM socket is provided.
4.6. Built-in Antenna
•
6 turns symmetric loop antenna. Center tapped.
•
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.

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
