content: I am planning to make punching machine for employees attendance. System verify the identity of the employees clocking in and out.I want to develop this system successfully. I see the option is raspberry Pi and EDP board for project? Which controller or development board will you suggest for this project.

content: Until you get some more useful replies I did aquick google searchwhich shows quite a lot of existing projects on github which could be a starting point.Thefirst oneused a Pi and he wrote his GUI in Tkinter which automatically makes me trust it more

content: Does it actually have to punch a card, or is for example a tap on token reader suitable? Might widen your search.Or does the employee get a punch if they are late?

content: Pretty easy to make one that reads RFID tags. If there's already a RFID system in place to unlock the door, there almost certainly would be an option to log when different tags are used.

content: This sounds like an engaging project. Hope it goes well for you.I don’t want to be a downer, but there may be some legal regulations you need to meet. Probably not too hard, but you don’t want a surprise to bit you at the last minute.Possible examples:- if you consider pivoting towards biometrics, that information may need special privacy provisions- interface terminal may have privacy implications (eg may not be OK to have a screen showing last N people who ‘punched’ in)- may have audit log requirements as it’s related to payment of staff- may need documentation in company business statements, employee handbooks or whatever- ‘punch in punch out’ may not line up with employee contracts- if the system will also be used for health and safety (eg checking everyone got out of the burning building) there may be extra requirements- consider how to handle disputes which may arise

content: Is there a need to re-invent the wheel? Do the employees have I.D. badges? Nearly everywhere I have worked since about 1988 had a system called Kronos. Multiple timeclock stations can be located around the factory and all sorts of data reports can be generated including payroll. It is nice that you want to extend the effort and learning experience. However, with all of the businesses that open, close, go bankrupt, etc it seems you could find a complete timeclock system on the used market cheaper than all of the time you will invest and still not have a system with the flexibility of Kronos.

content: And don’t forget emergency egress.A line of people queued up at the exit door during a fire or active shooter event - won’t look good on the insurance report.

Fire in the building structure, alarms requesting evacuation, proceed to nearest marked emergency exit, security access denied (after swiping card), temped to "break glass" on the door or emergency release at that point but just walked to the regular exit instead.

content: Quote from: richard.cs on April 29, 2022, 08:26:06 amDepends on the building safety laws, and interpretation thereof. Can I open such a door during an emergency exit while dragging a body? No, fails by one commonly used measure.

content: There are always two sides to an issue. A solid clock out record can assure that everyone is out safe, or provide cues about who and where to search for.There are issues with this of course but actions of this type are de rigor for well done emergency responses.
