Access Control Solutions for Doors, Turnstiles, Gates & Controlled Entry
BSD Infotech designs customized access control solutions around your premises, your people and your access requirements. We combine identification technologies — biometric, face recognition, RFID, NFC and smart cards — with the appropriate controllers, door locks, turnstiles, gates and software.
You do not need to decide the hardware first.
Tell us what you need to control, who needs access and how your existing system works. We help design the access control architecture and then recommend the hardware and software it needs.
What an Access Control System Actually Includes
Access control is not simply a reader installed beside a door. A complete system usually has several layers — and which ones your site needs depends on the requirement:
1Identification
Who is this? Face, fingerprint, RFID card or tag, NFC, smart card, UHF tag, or PIN and other supported methods.
2Access decision
Should they be allowed in, here and now? A controller and access control software apply user permissions and access rules.
3Physical entry control
What opens? Door lock, magnetic lock, electric strike, turnstile, flap barrier, gate or boom barrier.
4Management software
User management, access permissions, entry/exit records and reports — with attendance or visitor management where required.
5Integration
Links to existing applications: HR and attendance, visitor, membership, ERP or other systems through APIs, and customized applications where required.
Designed for your site
Not every project needs every layer or component. We select the technology and hardware according to your actual requirement.
Complete Access Control Solution Architecture
A typical architecture. The exact design depends on the site, the number of access points and the equipment selected.
Access Control Technologies We Can Work With
Biometric access control
Fingerprint-based identification and biometric access devices for controlled entry. See biometric and fingerprint solutions.
Face recognition access control
Face-based identification at access points where face recognition is appropriate — for example hands-free entry or face-based attendance. BSD Infotech has implemented face recognition solutions at institutions.
RFID access control
RFID cards and tags with readers at doors, turnstiles and gates. See RFID cards and tags.
NFC access control
NFC cards, tags, phones and readers for controlled access, such as membership entry. See NFC access control.
Smart card access control
Smart-card identification for access, often combined with other uses of the same card such as cashless payment. See smart card and RFID readers.
UHF access control
UHF tags where longer-range identification is needed and the project suits it — for example vehicle or gate entry. See UHF RFID readers.
These technologies are not interchangeable — each suits different sites, users and workflows. See the comparison below.
How Entry Is Physically Controlled
Door access control
A door can be controlled with an electric lock, magnetic lock or electric strike, a door controller, and a reader, biometric device or face recognition device, with an exit button on the inside. The exact combination depends on the door and the project.
Turnstile access control
Turnstiles can be connected with RFID, NFC, smart card, biometric or face recognition identification, depending on the selected equipment — for controlled pedestrian entry and exit.
Gate & barrier access control
Where appropriate, gates, boom barriers and vehicle entry can be linked with UHF, RFID, biometric or other supported identification. Compatibility is confirmed for the specific equipment.
Door Controllers: The Control Layer Behind the Door
In many installations the reader or biometric device identifies the person, while an access controller makes the access decision and operates the door hardware:
Controllers come in single-door and multi-door (for example 2-door and 4-door) versions. Larger installations use several controllers managed from centralized software. The exact architecture depends on the system selected. Examples of controllers we work with: the C3-100/200/300 IP-based access control panel and the SRB security relay box.
Access Control Software, Not Just Hardware
BSD Infotech develops software as well as supplying hardware. Depending on the project, the software can be configured or developed for:
- User management and card/device registration
- Access permissions by person, area and time — for example allowing or blocking a club member’s access based on membership or dues status
- Entry/exit records and access history
- Dashboards and reports
- Role-based access, e.g. administrators see all gates, gate staff see only their gate
- Attendance integration
- Visitor management integration
- Membership system integration
- Database, SMS and API integration
- Customized workflows and reports
Why customized software instead of the device’s default software?
The software supplied with a standalone device is often limited to that device. On multi-gate sites, customized software can provide:
- One central database for all gates, so users are enrolled once instead of being copied device to device
- Central reports, available beyond the local PC
- Rules the default software may not support — for example stopping the same person re-entering for a set time, so one enrolled user cannot let others through a turnstile
- Changes to access rules made centrally, without visiting each device
Not sure what your site needs? Tell us the number of doors or gates, the users and your current system.
Access Control + Attendance
When the requirement calls for it, access control and attendance can work together: an employee enters through a controlled door, the identity is captured, access is validated, the entry is recorded, and the attendance data is processed where configured. The same approach applies to schools, offices, factories, institutions and clubs. Not every access control installation includes attendance — it is added when it is needed. See school attendance and crowd control and fingerprint attendance across multiple offices.
Access Control + Visitor Management
Access control can also work alongside visitor management when required: visitor registration, authorization, identification, controlled entry, and entry and exit records. Not every installation includes visitor management. See our visitor management system.
Turnstile & Controlled Entry Solutions
BSD Infotech designs solutions where identification technology is connected with controlled pedestrian entry equipment such as full-height turnstiles, tripod turnstiles and flap barriers. Possible combinations, depending on the selected equipment and system:
- RFID + turnstile
- NFC + turnstile
- Smart card + turnstile
- Biometric + turnstile
- Face recognition + turnstile
For example, BSD Infotech implemented campus in/out management for a university using a full-height turnstile with biometric identification — and the university later ordered a second turnstile. In all, BSD Infotech has implemented turnstile, biometric, face recognition and UHF reader solutions across 20 institutions. Where a boom barrier is used, identification devices can be placed on both sides for entry and exit. See turnstile gates, flap barriers and boom barriers.

Which Access Control System Do I Need?
| If you need to control… | A typical starting point |
| One office door | Door controller + identification device + lock |
| Multiple employee doors | Centralized access control software + controllers + identification devices |
| High-volume campus entry | Turnstiles + RFID/NFC/biometric/face identification + centralized management |
| A school gate | Suitable identification + controlled gate or turnstile + attendance/security workflow |
| Factory entry | Employee identification + access control + optional attendance |
| A membership club | Member identification + access control + membership integration where required |
These are starting points, not fixed packages. The final architecture depends on your site requirements.
Choosing an Identification Technology
| Technology | How the person is identified | Typical use | Considerations |
| Fingerprint | Enrolled fingerprint matched on a device | Staff doors, entry linked to attendance, club facilities | Needs enrolment; each person must use the device individually |
| Face recognition | Face matched against enrolled images | Hands-free entry, face-based attendance | Camera placement and lighting matter; enrolment and consent |
| RFID | Card or tag presented to a reader | Doors, turnstiles, large user groups | Cards can be lent or lost — combine with rules or biometrics where needed |
| NFC | NFC card, tag or phone at close range | Membership and campus verification, mobile-based checks | Supported cards and phones; may need an app |
| Smart card | Card with a chip, contact or contactless | Access plus other uses on one card, such as cashless payment | Card cost and an issuing process |
| UHF | Longer-range tag reading | Vehicle gates, hands-free zones | Read range needs careful design; not intended for single-person door control |
There is no single “best” technology — which is why we understand the requirement before recommending equipment.

Customized Access Control Software & Integration
BSD Infotech works on projects that need customized applications, database and API integration, RFID/NFC/biometric integration, integration with existing software, customized reports and workflows, and integration with attendance, visitor or membership systems. Examples of work BSD Infotech has implemented or proposed:
- Club access where a member’s entry to facilities is allowed or blocked from the membership system, for example based on dues status
- Member verification by fingerprint at a club reception before the member can use the club’s outlets
- Face-match member authentication for a cloud-hosted club platform, with an audit trail (proposal stage)
- One smart card used both for door access and for payments on the premises
- An access control solution designed around a customer’s existing software screens
