Keeping track of hourly employees' work time is a breeze with a clocking-in machine. However, the types of machines vary greatly from the standard, small punch card system to complex fingerprint reader. The simplest type still uses weekly and monthly time cards for automatic stamping. Available on eBay, these smaller machines have either an analogue-style clock face or an LED display. The more computerised versions offer automatic time changes with the seasons and two types of ink for indicating "on time" and "late clocking in". Businesses that handle large numbers of employees or are concerned with security should use fingerprint clocking-in machines. These devices don't rely or cards so nothing is lost, and only the employee can clock himself or herself in. The system allows for faster flow through of employees at starting and ending times and it holds up to 800 fingerprints. Whether choosing a small or large system, a clocking-in machine can help you record employee work hours with less hassle and more accuracy.
