Noob here, need help!

Okay, so we are combining a card reader with a fingerprint scanner (5V TTL (GT-511C1) Fingerprint scanner) and the card reader is a normal magnetic car reader with serial port. We want to make a system that allows you to syncronize your fingerprint with an idendification card. The system have to reject you if your not old enough. The system also have to reject you if your fingerprint dosen't match your ID-card. Is this possible and how could we make and program this?

Please help. We are three students that needs your help and guidance as soon as possible.

Permission granted.

Sounds simple enough.

Is this possible

With the right hardware.

how could we make and program this?

I see. You came up with the idea, and want others to do the work. Is this how you do all of your homework?

Which ones?

Both have serial ports, and we were thinking about doing some multiplexing

We don't want you or someone else to make it. We just need gudiance or any kind of help.

Well, that certainly clears things up. Though, it would be far simpler to get an Arduino that has multiple serial ports, like the Mega.

Is it possible with our hardware?

How would I know. You did not bother posting a link initially, nor did you post one when I asked.

That would be in response to SPECIFIC questions, like "I have this device: http://somelinktosomehardware.com, that generates serial output. How can I connect it to the Arduino Xxxx that I have, and get the serial data?".

We already have Arduinos, but not like the Mega, we have Arduino Uno.
