From simple keypad readers to biometric scanners, modern access control allows you to decide granularly who can enter, where, and at what time. Here are the main technologies and how to choose the most suitable one.
Keypads: simple and affordable
They remain the most widespread solution for individual entrances or residential access: each user receives a personal code, which can be easily revoked if necessary without having to replace any physical components. The latest models also offer additional security features, such as a duress code (which opens the door while silently signaling an emergency) or high IP and IK ratings for outdoor installation.
RFID badges and tags: easier large-scale management
For offices, companies, and residential buildings with many users, badge or RFID tag readers (often featuring Desfire technology for increased cryptographic security) allow for centralized access management: activating or deactivating a lost badge takes just seconds from the management software, without having to change the lock or communicate a new code to all users.
Biometrics: maximum security, zero credentials to lose
Fingerprint or face recognition completely eliminate the problem of lost or duplicated credentials because the access "data" is the person themselves. It is an increasingly popular solution for critical access areas (server rooms, warehouses with valuable goods, laboratories) where precise traceability of who accesses and when is a requirement, not just a convenience.
Scheduled access control: times, days, and temporary permissions
An often underrated feature is the ability to limit a single user's access to specific time slots or certain days of the week, useful for example for cleaning staff, suppliers, or temporary guests. Similarly, group management allows you to grant a user access only to areas within their scope, without having to create separate configurations for each individual entrance.
Integration with burglar alarms: one system, more control
The latest access control systems integrate directly with the intrusion alarm control panel, allowing, for example, the automatic deactivation of an area's alarm when an authorized user opens the entrance with their badge, or receiving a notification if access occurs outside allowed hours even when the system is disarmed.
