Access Control Software

Modernize your personnel attendance control system. Entry/exit tracking with fingerprint, card, face recognition and QR code, time calculation, leave management and detailed reporting. I build HR platforms that bring personnel records, leave, attendance/timesheets, payroll, overtime and headcount budgeting under one roof. I turn entry/exit data from card and fingerprint readers into automatic timesheets and encode your leave and overtime rules into the system, with access permissions, activity logs and retention rules designed with data protection requirements in mind. As a freelance software developer in İzmir, Türkiye, I work online with businesses in İzmir and the surrounding region, and you talk directly to the developer throughout.

Frequently asked questions

Is time attendance software compliant with data protection law?

Time attendance systems process personal data, and biometric data if fingerprints or faces are used, so compliance must be planned together with the setup. In the software I implement technical measures such as role-based access, activity logs and retention and deletion rules. I recommend clarifying legal steps such as explicit consent, privacy notices and an alternative entry method with your legal team.

Can I keep using my existing card and fingerprint devices?

In most cases, yes. Common attendance devices offer an SDK or a data export interface, so I can bring entry/exit data into the software without replacing your devices. During discovery I review device makes and models and run a connection test if needed. For unsupported legacy devices I assess with you whether replacement is necessary.

Will it integrate with my timesheet and payroll software?

Yes, my goal is that timesheets are never re-entered by hand. Calculated working hours, overtime and leave data can be exported in the format your payroll software accepts or transferred directly via API. Payroll, leave and attendance can also be combined on one platform, and I define the integration points with you during discovery.

Can employees request leave from their phones?

Yes. I can build the application as an installable web app (PWA), so leave requests, timesheet views and announcements are available without downloading anything from an app store. Managers receive instant web push notifications for requests awaiting approval. If a separate iOS or Android app is required, I can include that in the scope as well.

Should I buy an off-the-shelf package or custom software?

If your shift and overtime rules are standard, an off-the-shelf package may be enough. If you have complex shift patterns, special overtime rules, several locations or need deep integration with HR processes, custom software is usually the better fit. In a free initial meeting I review your rules and tell you honestly which option suits you.
