The ATR480 Time Clock automatically calculates and totals employee time for businesses with up to 50 employees. With this time clock, you can set overtime policies, implement rounding rules, and deduct break time to accommodate your payroll needs. The ATR480 supports job costing and can be set to automatically adjust for Daylight Saving Time. This top-loading clock features automatic card positioning and easy-to-read imprints in standard (AM\/PM) or military (24 Hour) time. Employee time can be set to record in minutes or hundredths. A two-color printing option makes it easy to spot early and late punches. Use the built-in programmable buzzer or connect to an external signal device to notify employees about shift start and stop times. To enhance security, clock programming can be password protected and the clock case is secured with lock and key to prevent tampering. The built-in battery allows employees to keep punching, even during power outages. Bundle includes three two-color ribbons (one installed, two extra), 300 time cards, two 10-pocket time card racks, four keys, owners manual and power cord.
