Abstract
Description
[Technical Field]
[0001] The present invention relates to a working hour management method and a working hour management system. [Background technology]
[0002] An attendance management system is generally configured to manage the working hours of employees, including regular working hours, overtime hours, and the regular working hours and overtime hours for each project that the employee is responsible for. Various systems and methods have been known as technologies for configuring such attendance management systems. Summary of the Invention [Problem to be solved by the invention]
[0003] To provide a simple and low-cost attendance management program and attendance management system that uses a smartphone to read QR codes. [Means for solving the problem]
[0004] QR codes linked to each workplace are issued, and employees can record their arrival and departure times by scanning them with an attendance app on their smartphones, etc. QR codes and the like can be issued any number of times, and each time they are issued they are replaced (expired) with the latest one. QR codes and other such codes are expected to be issued by printing them on paper, displaying them on the screen of a tablet device or the like, or displaying them in a web browser or the like. When issuing a card using a tablet device, a QR code is generated by performing the issuing action (touching the screen, etc.), and the code is invalidated when the code is scanned with an attendance app on a smartphone or other device and the attendance is registered. This will ensure that individuals are identified and present at work, and prevent fraudulent use. Display on a browser, etc. is done by sending images such as QR codes from the attendance management server to various online services. [Effects of the Invention]
[0005] QR codes and other information issued and linked to each workplace can be printed on paper or displayed on an information terminal such as a tablet, eliminating the need for time cards for each worker. In addition, each worker's arrival and departure times are sent to the management server, and the calculation of working hours and overtime hours is performed automatically, which reduces the time and labor costs required to calculate the hours from each worker's time card. [Brief explanation of the drawings]
[0006] [Figure 1] Appearance of QR code reading by smart device [Figure 2] FIG. 10 is a flow diagram showing processing by a smart device application that performs attendance management using QR codes or the like. DETAILED DESCRIPTION OF THE INVENTION
[0007] Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
[0008] (Embodiment) FIG. 1 is a diagram showing the registration of attendance management data. When you start the attendance management program, a screen for reading QR codes, etc. will appear. By scanning a printed document containing a QR code or other code associated with the business location using a smart device, attendance data can be automatically sent to the management server. In addition, if the establishment in question is not registered as an employee, it can be transferred to employee registration.
[0009] The devices to which the present invention can be applied are not limited to personal computers, smartphones, and tablets, but also include various camera-equipped devices. Electronic devices are envisioned. [Industrial Applicability]
[0010] The present invention can be used in an attendance management system that manages the attendance of workers working for a company or the like, an access control system that manages entry and exit to rooms within a building, and the like. [Explanation of symbols]
