I have 4 turnstiles with two QR scanners(Two ways).
Need make program what will online read information from scanners and will send request to MS SQL about access. if true will open turnstile, if not - then not.
I have SDK for C#.(Attachment)
Request to MS SQL i will write later.
Better if this program will wok under Ubuntu. But if can't can use Windows.
I will make this app for you in 4 days, but i will need more details about the request, (Exp: what to check in MSSQL, what does the QR Code return after reading it...etc), hope you choose me for your work.
regards.
