Hi. I am currently doing project regarding Fingerprint Based Attendance System among students. There will only be scanners on each room and I will be using LAN to connect these scanners to the main database. I am having trouble with determining what type of scanner and micro controller to be used and how to interface them with the database. Ideas about this topic will be highly appreciated. Thank you!
 

how many scanners you are using ..You can go for PIC micro controllers otherwise if you are using 1 then go forAt89s52..
For biometric finger print scanner used R303A..i have worked on that. it works fine..
 
i will be using one fingerprint scanner per room. so each scanner will have its own microcontroller. thank you so much the help. :)
 

Hi,

If you are using the LAN to connect these scanner, you have to built the TCP/IP stack to talk to the database PC. In this case, you can try Microchip 18F97J60 to connect these finger printers to the single database.

You can keep your Finger Print controllers as Server slave and Database PC/ Laptop as Master Client. This can be done easily with this part.
try this one.
 
Thank you for helping. Is there a specific model of fingerprint scanner to be used with microchip 18F97J60? And can i also connect an LCD Display using this? the LCD display would indicate whether the student's attendance is valid or not.
 

R303A Series Fingerprint Identification Module can be connected with any micro controller .Before using read the manual..it is very easy to interface
 
Its ok..If you find any difficulty in anything ..u can ask..
All the Best
 
Hi,

As aameer told, you can interface the LCD and finger print module with any microcontroller. LCD requires 11 I/O pins. 18F97J60 has 70 I/O pins. As far as i concern, You can choose this one and try to implement the server slave in it and print the student database in the LCD simultaneously. This will make your Job easy.
 

how to interface microcontroller with finger print module.....do u have any material plz give me...
 

i am trying to interface r303a with 89c51...can you plz tell me how to proceed as i have not worked on this module...if possible plz send the code to jai.deadman666@gmail.com...
