I Want To Install A 'Punch Card System' In Our Factory Premises For Attendance..

Hi All,
I am working as a HR Manager for an upcoming Steel Plant in the extended outskirts of Bhubaneswar. I want to install a 'Punch Card System' in our Factory Premises for Attendance as well as Time-Keeping purposes.
Can anyone please suggest me which particular device would best suit my requirements? Please also suggest me the make, model & price of the devices that are mostly being used by different companies. Thank U all..

Thanks a lot to U both, 'earlystar' & 'rkdhiman', for your valuable suggestions. But the other fellow members really disappointed me. I was actually expecting to be overflooded with responses from everywhere :-(
