7. CRITICAL EVALUATION
The project was aimed at proving that there will be less absenteeism in learning
institutions provided that they have installed the fingerprint recognition system. The use of
GSM has effectively brought about a better class attendance as student attendance is sent to
their parents' mobile phones via an SMS alert.
The project also reveals that there is a successful comparison of the scanned fingerprints on
the device and the one stored in the database. But some key questions will always arise about
the system which when we say is good others may take it to be otherwise.
Although, from a technical perspective, there is a need to substitute:
Use an optical fingerprint sensor system instead of the biometric sensor
We are dealing with only fingerprints and the biometric sensor is such a generalized term.
There are three types of fingerprint acquisition equipment, that is, ultrasonic fingerprint
sensor, semiconductor fingerprint sensor and optical fingerprint sensor. The optical
fingerprint system is made up of flash, optical fingerprint sensor and DSP processor. The
system has a 64kB user flash memory which can manage fingerprint templates not exceeding
770 in number. This system can enhance the quality of images for both wet as well as dry
fingers and can perform other functions like fingerprint download, fingerprint deletion,
fingerprint upload, and fingerprint verification among other functions.
The common jobs for a fingerprint scanning system include first getting an image of the
finger and secondly determining whether the pattern in the image match with the other pre-
scanned images. The optical scanner using a charged coupled device (CCD) that is made up
of photosets that respond to light photons by generating an electrical signal. The scanning
begins when the finger is placed on a glass plate hence allowing a CCD camera to take a
picture that generates an inverted image of the fingerprint.

Use the P89V51RD2 microcontroller
This is line with specifications of optical fingerprint system for best output of the system. It
has 1024 bytes of data RAM plus 64kB flash and is usually In-Application Programmable
(IAP) that allows the reconfiguration of the flash program memory on running application.
The microcontroller runs the following functions:
1. Powering up and initializing the dependent modules.
2. Checking for interruptions and errors while the modules are initializing.
3. Commanding the fingerprint module to work in harmony with the software
interface.
4. Enabling data transmission through a wireless network.
Project problems
1. Selecting of the hardware and software framework to be used to achieve desired
results.
2. Keeping automation test cases up to date as daily there are more and more
development cycles as setting the software and hardware doesn’t mean that they will
work.
