RFID systems use a reader, tag, or card to grant access to a person or object. The reader communicates with a central software system to verify the credentials and decide whether access should be granted or denied.
These systems are great for high-security premises and help businesses meet government or internal security regulations. They are also easy to administer and offer flexible credential options.
Security
Before RFID technology was available, venues had to rely on well-trained parking attendants to verify credentials and let patrons in. Unfortunately, this system was prone to errors, leading to long wait times and frustrated patrons late for their event.
RFID access control systems are designed to work with sensors, readers, and tags that communicate with each other using radio frequency signals. The user’s RFID credential, a card or fob, is activated when it is held up to a reader configured to recognize the specific data being transmitted by the tag.
This process enables the reader to cross-reference the data it receives from the tag with a database of authorized credentials and identification numbers to grant or deny access. The reader also activates a signal that can trigger an alarm or additional security measures, such as automatically locking a door behind the user. These features improve security, reduce operational costs, and improve customer satisfaction.
Scalability
The scalability of RFID access control systems is an important feature to consider when evaluating them. This means that the system can be expanded as the organization grows, which can help reduce costs by avoiding the need for a complete replacement of the entire system.
A card reader emits a radio frequency energy field that powers a copper aerial inside the access card to verify access. This energizes the card chip containing an ID number and other data. The reader then transmits the data to the door lock, which grants or denies entry based on the information.
Additionally, RFID systems can allow administrators to monitor and adjust permissions remotely via a web portal or mobile application. This enables security teams to manage their workflow more efficiently and ensures that only authorized personnel can access sensitive areas. This is especially beneficial in healthcare environments where hygiene is a priority. These systems also eliminate the need for traditional keys, reducing the risk of unauthorized access due to lost or copied keys.
Convenience
Unlike traditional access systems that rely on bar codes or proximity readers, RFID solutions allow contactless operation. Residents and employees can easily gain access by tapping a credential against a reader.
RFID tags contain microchips that store digital credentials. Each tag is connected to a unique person’s identifier and can transmit this data to a reader. The reader then compares the information transmitted to a database. If it matches, the system sends signals to the electric door release mechanism, unlocking it for entry.
Many modern RFID access control systems offer remote management through a secure application or online portal. This allows property owners to approve and adjust user permissions without being on-site. This is particularly effective for businesses accommodating fluctuating shift schedules and seasonal staffing. It is also helpful for service providers, such as dog walkers or house cleaners, who often require temporary digital keys.
Cost
Many factors must be considered when evaluating the cost of an RFID system. These include initial setup costs and ongoing fees for software, subscriptions, and maintenance. Additionally, it’s essential to consider the costs of any additional infrastructure and hardware requirements.
RFID access control systems operate by transmitting an interrogation signal to the reader and receiving a response from it. This identifies the card and sends its data to the control panel, which decides whether or not access is granted.
The best systems offer a user-friendly interface, making it easy for administrators to manage users and permissions. They also feature high-level encryption, reducing the risk of hacking. Finally, they should be scalable to accommodate a growing number of employees. This is especially important for organizations that manage assets in multiple locations. They can also be used to track employee movements. This is particularly useful in high-security environments like server rooms or cash storage areas.
