Card access and turnstiles at school: how to plan student entry

What does card access solve at a school?

The problems school principals mention most often are not knowing who enters the yard and building during class hours, students leaving without permission, and parents asking whether their child has reached school. The attendant at the door cannot recognize everyone at busy times.

In a card access system, every student and staff member has a card. When the card is tapped at the main entrance turnstile, the entry time is recorded. The system can optionally send the parent a short notification. During class hours, the turnstile opens only with a staff card or under the security guard’s control; someone coming from outside cannot walk straight into the building.

This system does not replace student attendance tracking, but by recording entry and exit times it supports classroom roll call. When a student leaves with their card during school hours, the administration sees it in the report. In primary schools, it is also possible to restrict exit so that it happens only with a parent; in that case, the student’s card will not open the turnstile in the exit direction until the end of classes.

How many turnstiles are needed?

The number of turnstiles is determined not by the school’s student count but by the crowding at the morning entry time. Most students arrive in a short window before the first bell. If you know how many students must pass in that window and how many passes each turnstile can handle per minute, you can calculate the number.

Turnstile manufacturers state a per-minute throughput, but this figure is measured under ideal conditions. Students who search for their card in their bag or try to pass together with a friend lower the real capacity. Doing the calculation below the catalog figure and keeping one turnstile in reserve prevents the morning queue.

In schools with double-shift education, both exit and entry happen at the same time around noon. In that case, the turnstiles need to work in both directions, and exit and entry should be separated into different lanes.

Expert note: Stand at the school door for five minutes at the morning entry time and count how many students arrive. This simple observation shows the number of turnstiles more realistically than the catalog calculation.

Turnstile type and school environment

The most common choice in schools is the tripod turnstile: it is sturdy, easy to maintain and lets people through one at a time. At the main entrance, a sliding-wing turnstile is a more attractive and faster option, but the safety sensors must be well adjusted so children do not get caught in the wings. A full-height turnstile is used at outdoor entrances such as the yard gate, especially to prevent uncontrolled entry outside working hours.

Schools always leave a wide accessible and service passage next to the turnstile. Students in wheelchairs, parents with strollers and suppliers bringing materials pass through this gate. This gate also opens with a card or under the security guard’s control.

If the turnstiles are outdoors in the yard, outdoor models that withstand the heat of a Şanlıurfa summer and the rain in winter should be chosen, and a canopy should be built over them.

Cards, parent notification and lost cards

A student card is usually a contactless RFID card; it is read by radio waves when brought close to the reader. The same card can also be used in places like the canteen, cafeteria and library. The student’s photo and name can be printed on the card; the attendant at the door can use this photo to see whether the student tapping the card is its owner. In the computer, the card is matched with the student’s class and parent.

If parent notification is wanted, the system can send the parent a short message or app notification at the moment of entry and exit. Before turning this feature on, it is right to inform parents in writing and get their consent. How the notification service is provided and what it costs vary with the software used.

Lost cards are common. When a card is lost, it should be canceled in the system immediately and a new card issued. It makes things easier if the school administration has a simple procedure for printing a new card and a stock of spare cards.

Visitor, parent and staff entry

Parents and visitors cannot pass through the turnstile without a card during school hours. At the entrance, the attendant takes the visitor’s ID details and gives a daily visitor card. The card can open passage only to the administration floor or a specific section, and is taken back at exit.

Teachers and staff enter with their own cards. The same card can also be used at doors such as the teachers’ room, laboratory, library storage, archive and server room. If wanted, staff entry times can be reported for attendance tracking.

If a barrier or motorized gate is used at the yard gate for school buses and supplier vehicles, the same access system can manage vehicle entry too.

If the school yard is opened in the evenings and on weekends for sports or course activities, a separate access plan is defined for those hours. Course teachers and participants are given cards that are valid only at those times. This way, the building and yard are opened outside school hours with knowledge of who is using them.

Emergency evacuation and safety

In a fire or earthquake drill, hundreds of students need to leave the building within a few minutes. The turnstiles must not be an obstacle at that moment. For this, the turnstiles are planned to be released when they receive a signal from the fire alarm system or by the security guard’s button.

Points to watch for in planning:

• Turnstiles must be releasable by the fire alarm and manually
• Whether the turnstile should move to the released position in a power cut should be assessed
• The turnstile lane must not be the only exit on the evacuation route
• The accessible passage gate must also be usable as an emergency exit
• The release of the turnstiles should be tested in a drill
• Jam sensors on sliding wings should be tested regularly

Student data and KVKK

Student cards, entry times and photos are personal data; because students are children, extra care is needed in processing this data. Parents must be clearly told what data is collected, who will access it and how long it will be kept. Using cards in schools, rather than biometric methods such as fingerprints or face recognition , simplifies both the way it works and data responsibility.

In public schools, the procurement process and technical specification also matter. Desa Bilişim designs turnstile, card access and camera systems together for schools in Şanlıurfa; we can examine your school entrance on site and draw up a plan according to your needs.
