Poker room comp system - how to keep track of played hours?

[playersare]

B&M comps are usually tracked at the front desk. players swipe in and out and the amount of time spent in the room is recorded (and management can vary comp rates by game stakes as needed). if you don't have the technology budget, handwritten time cards can work too - almost like a punch clock at work.

a few places also put barcodes on cards and someone comes by to scan every player once every 30 or 60 minutes.
