A time clock, sometimes known as a clock card machine or punch clock or time recorder, is a mechanical (or electronic) timepiece used to assist in tracking the hours worked by an employee of a company.
In regard to mechanical time clocks this was accomplished by inserting a heavy paper card, called a time card, into a slot on the time clock. When the time card hit a contact at the rear of the slot, the machine would print day and time information (a timestamp) on the card.
One or more time cards could serve as a timesheet or provide the data to fill one. This allowed a timekeeper to have an official record of the hours an employee worked to calculate the pay owed an employee.
The terms Bundy clock, bundy clock, or just bundy have been used in Australian English for time clocks. The term comes from brothers Willard and Harlow Bundy.

History
Origins
An early and influential time clock, sometimes described as the first, was invented on November 20, 1888, by Willard Le Grand Bundy, a jeweler in Auburn, New York. His patent of 1890 speaks of mechanical time recorders for workers in terms that suggest that earlier recorders already existed, but Bundy's had various improvements; for example, each worker had his own key. A year later his brother, Harlow Bundy, organized the Bundy Manufacturing Company, and began mass-producing time clocks.
In 1900, the time recording business of Bundy Manufacturing, along with two other time equipment businesses, was consolidated into the International Time Recording Company (ITR).
In 1911, ITR, Bundy Mfg., and two other companies were amalgamated (via stock acquisition), forming a fifth company, Computing-Tabulating-Recording Company (CTR), which would later change its name to IBM.
The Bundy Clock (see image left) was used by Birmingham City Transport to ensure that bus drivers did not depart from outlying termini before the due time; now preserved at Walsall Arboretum.
In 1909 Gillette explained about the state of the art around time clocks in those days:
An example of this other form of time clock, made by IBM, is pictured on the right. The face shows employee numbers which would be dialed up by employees entering and leaving the factory. The day and time of entry and exit was punched onto cards inside the box.
Mid 20th century
In 1958, IBM's Time Equipment Division was sold to the Simplex Time Recorder Company. However, in the United Kingdom ITR (a subsidiary of IBM United Kingdom Ltd.) was the subject of a management buy-out in 1963 and reverted to International Time Recorders. In 1982, International Time Recorders was acquired by Blick Industries of Swindon, England, who were themselves later absorbed by Stanley Security Systems.
The first punched-card system to be linked to a Z80 microprocessor was developed by Kronos Incorporated in the late 1970s and introduced as a product in 1979.
Late 20th century
In the late 20th century, time clocks started to move away from the mechanical machines to computer-based, electronic time and attendance systems. The employee either swipes a magnetic stripe card, scans a barcode, brings an RFID (radio-frequency identification) tag into proximity with a reader, enters an employee number or uses a biometric reader to identify the employee to the system. These systems are much more advanced than the mechanical time clock: various reports can be generated, including on compliance with the European Working Time Directive, and a Bradford factor report. Employees can also use the gadget to request holidays, enter absenteeism requests and view their worked hours. User interfaces can be personalized and offer robust self-service capabilities.
Electronic time clock machines are manufactured in many designs by companies in China and sold under various brand names in places around the world, with accompanying software to extract the data from a single time clock machine, or several machines, and process the data into reports. In most cases local suppliers offer technical support and in some cases installation services.
More recently, time clocks have started to adopt technology commonly seen in phones and tablets - called 'Smartclocks'. The "state of the art" smartclocks come with multi-touch screens, full color displays, real time monitoring for problems, wireless networking and over the air updates. Some of the smartclocks use front-facing cameras to capture employee clock-ins to deter "buddy clocking", a problem usually requiring expensive biometric clocks. With the increasing popularity of cloud-based software, some of the newer time clocks are built to work seamlessly with the cloud.

Types
Basic time clock
A basic time clock will just stamp the date and time on a time card, similar to a parking validation machine. These will usually be activated by a button that a worker must press to stamp their card, or stamp upon full insertion. Some machines use punch hole cards instead of stamping, which can facilitate automated processing on machinery not capable of optical character recognition.
There are also variations based on manufacture and machine used, and whether the user wants to record weekly or monthly recordings. The time cards usually have the workdays, "time in", and "time out" areas marked on them so that employees can "punch in" or "punch out" in the correct place. The employee may be responsible for lining up the correct area of the card to be punched or stamped. Some time clocks feature a bell or signal relay to alert employees as to a certain time or break.
Fraudulent operation of time clocks can include overstamping, where one time is stamped over another, and buddy stamping, where a friend clocks in another member of staff.
Self-calculating machines
Self-calculating machines are similar to basic time clocks. Nevertheless, at the end of each period the total time recorded is added up allowing for quicker processing by human resources or payroll. These machines sometimes have other functions such as automatic stamping, dual-colour printing, and automated column shift.
Software based time and attendance systems are similar to paper-based systems, but they rely on computers and check-in terminals. They are backed up with software that can be integrated with the human resources department and in some cases payroll software. These types of systems are becoming more popular but due to high initial costs they are usually only adopted by large business of over 30 employees. Despite this they can save a business a lot of money every year by cutting down errors and reducing administration time.
Mobile time tracking
With the mass market proliferation of mobile devices (smart phones, handheld devices), new types of self-calculating time tracking systems have been invented which allow a mobile workforce - such as painting companies or construction companies - to track employees 'on' and 'off' hours. This is generally accomplished through either a mobile application, or an IVR based phone call in system. Using a mobile device allows enterprises to better validate that their employees or suppliers are physically 'clocking in' at a specific location using the GPS functionality of a mobile phone for extra validation.
Biometrics
Biometric time clocks are a feature of more advanced time and attendance systems. Rather than using a key, code or chip to identify the user, they rely on a unique attribute of the user, such as a hand print, finger print, finger vein, palm vein, facial recognition, iris or retina. The user will have their attribute scanned into the system. Biometric readers are often used in conjunction with an access control system, granting the user access to a building, and at the same time clocking them in recording the time and date. These systems also attempt to cut down on fraud such as "buddy clocking." When combined with an access control system they can help prevent other types of fraud such as 'ghost employees', where additional identities are added to payroll but don't exist.
