Home/Access control, turnstiles and payments
Paid access control,from ticket to report
We build the complete system for a paid or controlled entrance: the turnstile firmware, card or cash payment, the QR ticket, time attendance and reporting. You can find the equipment on gss.ro and turnicheti.ro.
From payment to report, in 5 steps
Every part of a controlled entrance
We can build all of them or only the ones you are missing.
Turnstiles and gates
Turnstile control through our own controller, with remote firmware updates.
- ESP32 controller and relays
- application on a PC next to the turnstile
- central control for all entrances
QR-code tickets
Online purchase, ticket by e-mail, scanning at the entrance and reporting, in a single application.
- installable web app (PWA)
- Android app for scanning
- sales and passage reports
Card payment
A POS at the turnstile, linked to the application that opens access only after the payment is accepted.
- POS built into the access flow
- online payment for tickets (in progress)
- confirmation and log for every payment
Cash payment
A kiosk with a banknote and coin acceptor that opens the turnstile after payment.
- banknote and coin acceptors
- Arduino or ESP32 controller
- our own schematic and circuit board
Time attendance and access control
Administration of existing attendance and access systems: users, readers, databases.
- ZKBio Time
- database cleanup and repair
- remote access over VPN
Reporting and alerts
Passages, takings and errors in one place, with a phone alert when an entrance stops working.
- centralized reports
- push notifications
- a log on every turnstile
Entrances we have delivered
Measured figures only. Projects in progress carry their own status label.
QR ticket and card payment access control at 5 turnstiles
An application on each turnstile, a POS for card payment, central control and ESP32 firmware updated remotely.
Banknote and coin payment kiosk for turnstiles
A banknote and coin acceptor that drives the turnstile; the Arduino version is installed, the ESP32 version with monitoring is in progress.
Online tickets with QR codes
Purchase, tickets by e-mail, scanning at the entrance and reporting. Public demo with simulated payment.
Secure time attendance and access control
The attendance database was cleaned and repaired on a copy, then applied only after confirmation and with a backup taken first.
Turnstiles, gates and readers
The access control and payment equipment is available in the Grid Security online stores. Here we build the part that connects it: firmware, applications, payments and reporting.
We work with Claude here too
Claude writes the turnstile applications, the central control and the firmware, and analyses the logs when something goes wrong in the field. We do the wiring, installation and tests with the reader and relay, on site.
What clients ask us
Can you connect an existing turnstile to card payment?
Yes, if the turnstile has a control input. We place a controller between the POS or QR reader and the turnstile, and access opens only after the payment is accepted.
What happens if the internet goes down?
It depends on the configuration; we settle it during the assessment, for each entrance, together with what should happen during a power or network outage.
Can people pay in cash as well?
Yes. We built a kiosk with a banknote and coin acceptor that opens the turnstile after payment.
Do you work with existing attendance systems?
Yes. We administered a ZKBio Time system at a public institution: users, readers and database cleanup.
No entrance goes into service without a test on every turnstile.
Have an entrance to automate?
Tell us how many access points you have, how people should pay and which reports you need.
