Fingerprint scanner for arduino

Hello
I was wondering if I could use this or something similar cheap fringerprint scanner with arduino.
I know I could use GT-511C1R but I'd like to use something cheaper.

Thanks

Get data sheets and find out how much data space is required for one scan. An ordinary Arduino may not have the required amount of RAM.

What do you want to do with a scan? You may need a SD card for the data to compare the scan, and eventually much processing power and RAM for rotating and shifting the images before comparison. The more expensive scanners may include all that, so that they can tell you immediately whether the current scan matches any previously taken scan.
