5.3 Card scanner - RF ID eas Inc
The USB modelemulates a keyboard and keystrokes the card’s ID and/orsite code
to the cursor’s location on the screen.The readercan be configured to add
keystrokes before and after the card’s data. The serialversion, available in RS-232,
Ethernet, or USB Virtual Com, delivers the card’s data in ASCII.
6 Database

of 34
First, start by doing the LABViewtutorial. At http://www.ni.com/white-paper/7466/en
So that u will get the hang on howthe LABViewworks. And some basic functions of the
LABViewto make your work easier.
Secondly, do some research aboutthe projectand download the LABViewtoolkits needed
for the project.
Start of the Project
I used a card scannerinstead ofa fingerprint readerbecausethe
fingerprint readerhas notarrived yet.
Make a simple database.
Start the projectby making a simple database table at Microsoft Access,called “Student”.
Which contain 3 columns,“Student Name”, “Admission Number”and “Card Number”. And
the change the file type of .dsn.So the LABViewis able to call the database table.
The Card Number can getit from the LABViewcode of the card scanner (Given by Mr Ang).
By scanning the card to knowwhat is the card numberofyour student card. So that it able
to knowwhich student tapped in. At this partyou, also need to read up on SQL statements
on how it works. http://www.w3schools.com/sql/sql_where.asp
If notyou will might have a hard time doing at the later part of the project.
At the same time Download 2 toolkit called “ VISA” and “Database Connectivity “. VISA
toolkit is too call USB instrument. While Database connectivity is for calling database from
Microsoft access and more to LABView.

of 34
File Name:USB Serial Read.vi
So the LABViewis able to read the admission number from the “Student” database table
and display the student information onto the Table (on the front panelbelow).
File Name:FYP.vi The Pink box is SQL statement.

of 34
Main VI: open connection.vi, selectdata.vi, data variant to data, close connection.vi
Combine with card scanner.
After calling the database table is successful.Combine it with the card scannerLABView
code.So when a card is scanned,the LABView is able to read the card number from the
“Student” database table and display the student information onto the Table (on the front
panelbelow). File Name:FYP_2.vi
Main VI: open connection.vi, selectdata.vi, data variant to data, close connection.vi

of 34
Now the modification of the LABViewcode will be in the “True & False”case structure
(which is the inner box (Above)). Outside of the “True & False”case structure will remain the
same till the fingerprint readerarrive.
Time In.
From the database table at the Microsoft access add on a newtable, called “Attendance”.
This table contain 5 columns.3 columns will be the same as the “Student” table, and adds
on “Time In” and “Time Out”.
This table used onlywhen the studenttaps their card and the Time In will be shown.
The LABViewwill pick up which student tapped in, at the “Student” database table and
insert the student’s name,admission numberwith the Time In into the “attendance”
database table. At this pointthe Time In and Time Out will be the same timing. Because the
on the later part the Time Out will be update when the studenttap out.
File Name:FYP_4.vi
The image belowshows the changes in the “True & False”case structure.

of 34
Main VI: open connection.vi, selectdata.vi, data variant to data(s), insert data.vi, close
connection.vi
Time Out
At this partneeded to create anotherdatabase table which is called “Attendance Record”.
So when the student tap out, it will able to keep a record of the student from whattime to
what time this studenttapped in and outon which date. And delete the data at “Attendance”
database table. So it will not keep updating the time out even if this student taps in the
second time. The “Attendance Record”table will also be using at web service (point 7)
This part needs more VIs. First, need to check whetherthe studenthave alreadytapped in.
The highlighted box (SQL statement) is calling the “Attendance “database table and getthe
card number(which just scanned).And it checked through execute query.vi, get
properties.vi and Fetch recordsetdata.vi. (At the highlighted triangle tool)At the fetch
recordsetdata.vi will send outan array (data). If it is an empty array, it will showTRUE (the
student have not tapped in before) so needed to insert this student into the “attendance”
database table. If showFALSE (the student have tapped in before) so needed to update the
Time Out of this student and keep the record ofthis studentat “Attendance Record”
database table. At this point, needed another“True & False”case structure.

of 34
There are no changes on the front panel.
File Name:FYP_5.vi
Main VI: open connection.vi, execute query.vi, getproperties.vi, Fetch recordsetdata.vi and
free object.vi
Inside this new “True & False”case structure.
At the True case,is where the studenthas not tapped in before. Therefore, it needed to
insert the student information with the Time In into “Attendance” database table. This is
similar with the Time In part, just that you putthe insertdata.vi inside of the “True & False”
case structure.
Main VI: Insert data.vi
At the False case,is where the studenthas tapped in before. Therefore, it needed to update
the Time Out of this student. And keep it as a record and insertit into “Attendance Record”
database table, and delete the data at “Attendance” database table. So that the students

of 34
able to taps in the second time. This part needed more time to do.
Main VI: update data.vi, selectdata.vi, data variant to data(s), insertdata.vi, and delete
data.vi.
7 Capture student image
When the studenttaps in, it also able to capture the student faces. At the database table
“Attendance” and “Attendance Record”, needed to add on one column call “Image”. The
“Image” column will showwhere the image been stored.It will showsomething like this:
“C:UsersmyProjectDesktopFYP Project (IMPT)ProjectsImage123.png” at the database
table.
At the same time, you needed to download a toolkit call “IMAQdx”. So that it able to run the
camera on LABView.
The Boolean button mustnot be turn on,as it acts as a tool to stop the camera case
structure to keep on looping.

of 34
File Name:FYP_6
The capture image is done within the “True & False”case structure which at the same
location where student information and Time In is. Now is just need to add in another
column for the “Image” which mention at the beginning.So that it will insert together with the
student information and Time In into the “Attendance” database table.
And the image will automatic save into the location (folder) you want.

of 34
Main VI: IMAQdx open camera.vi, IMAQdx configure grab.vi, IMAQdx grab.vi, IMAQdx start
acquisition.vi, IMAQ write file.vi

of 34
8 E-mail Alert
E-mail Alert is to alert the administrators to knowwhich student did not come at a certain
time.
Before starting on to this part, read a bit aboutSMTP to understand howemail
messages are sent,otherwise you'll probablyfind that your messages don'tget
delivered and you won't knowwhy.

of 34
9 Web Services
Web Services is to allow administrators to access into studentrecords through the web, by
typing in the studentadmission number. The LABViewwill getthe data from “Attendance
Record”database table which was done at Database part(point 5).
Do the tutorial before starting to move onto the project. At http://zone.ni.com/reference/en-
XX/help/371361H-01/lvhowto/build_web_service/#Creating_VIs_WS
Making Web Services is just like calling the database (which is almost the same done in the
beginning ofthe project and display it on the table at LABView.
First, code the LABView on howu wants the program to display your database.
Formine, type in the studentadmission numberand it will display that studentattendance
records.

of 34
Second,make sure the program run normally (no errors) on LABView,before putting it onto
the web.
Third, put the program onto the web.
Go to tools > options
Then u will come to this window. And click web server. The rest can leave it. Then click OK.
Enable the web server by clicking the appropriate checkbox. The default port
number for the web server is 80. U can change to other port number.

of 34
Specify a list of client IP addresses that are allowed to access the Web Server.
Each IP address may be granted controlling privileges, viewing only privileges, or
denied access. An asterisk (*) as shown is the Visible VIs and Browser access list
that grants access to any IP address.
Click okay after setting.

of 34
Go to tools > web publishing tool
You will come to this window.Select the VI to display on the web and ‘Tick’ Embedded.So
the usercan control it on the web. And click next.

of 34
You can change the title and the HTML contentfor the Web page.And click Next.
You can change the file name which changes the URL also. And click Save to Disk > OK.

of 34
This is howit looks like on the Web. *Make sure the VI is open* so that the Web will run
properly. After typing in the new admission number,a black tick will appearbelowthe “Edit”.
Make sure click on the tick before running it. (Unable to screenshotto showit here)

10 Problem Encounters & solutions
1. At the very begin of the project, cannotopen the file to display on LABView.
Because it is the wrong type of file . The file needs to be in .dsn file type.
2. Unfamiliar with Lab view. Because a lot of tools was still unknown to me.
All I can do is to Google the name/howitworks. Or go to NI forum.
3. SQL statements.
Find tutorial for SQL statements.
4. SMTP Server
Need to understand howthe SMTP server sends the email works by looking through
the tutorial.
5. LABViewof the send emailis working,butcannotsend outemail to personal
account.
6. When running LABView,atthe partwhere running the camera it will promptyou
where you want to save the image.
7. Do notknowhow to use LABViewto run with fingerprint reader.
