NFC & RFID Tags for Access Control Management

No comments

In the fields of physical security and information security, access control (AC) is the selective restriction of access to a place or other resource. The act of accessing may mean consuming, entering, or using. Radio frequency identification (RFID), especially those with near field communication (NFC) technology, are often used in access control management. They provide security protocols that allow access only to people with clearance. These people might clear security by using an ID card or another device implanted with an RFID tag. Whether you need to keep a gated community secure or track people at a large event, there are many RFID options for access control management. For example, a gated community might distribute RFID tags for residents to put in their cars. These tags allow them to clear the security gate and enter the community. Access control ensures that no one can enter a restricted area without physical authorization. Hospitals are also now making a push to put NFC and RFID technology in place to increase medical security for patients and doctors alike.

NFC Access Control Tags

Near field communication (NFC) technology is used for multiple applications, especially for protecting online security. This technology employs one NFC reader and one NFC card or key. The key is normally coded with the tag data, which contains the data for authorizing the holder to access the designated room or area. That key is tapped over the NFC reader, which reads the data with the aid of NFC communication protocol sets, and grants access to the authorized person. This communication isn’t limited only to authenticating and granting the access to the authorized person, but records the access data, time, period of access, and many other parameters.

There are different types of readers that are used in access control applications; among those readers, an IP-based modern access control reader is a highly featured, secure and reliable access control device available in the market. This reader can easily be integrated into an IT network for achieving the robust and secure access control with many additional security and operational features. A smart card is also being used in NFC-enabled devices, such as tablets, mobiles, and laptops to access cloud-based network and system resources over the internet. In this access control system, the smart card data is transmitted over the internet to the centralized location for granting of access into the entitled cloud computing resources.

The latest form of NFC access control system is being managed through the mobile applications installed on smart devices. Those mobile applications act as the key or a data tag for the NFC reader. When the mobile is swapped or tapped over the NFC reader, a communication channel is established over the air interface, and data transactions take place to authenticate the authority of the user to access the secured area, resources, or applications.

Access Control Management

The technicalities of RFID in access control management can be difficult to understand. They involve a lot of industry-specific language and concepts. Permission to access a resource is called authorization. Locks and login credentials are two analogous mechanisms of access control. However, the main idea isn’t a complicated one. An RFID system involves a reader connected to an antenna. This antenna sends out a radio signal to a tag that bounces the signal back with new information. This information is then sent to a secondary system, which interprets the data in the RFID tag to put actions in motion.

In the world of access control management, an example might be a keycard to an apartment complex. Residents swipe a keycard embedded with an RFID tag. This tag is read via a radio signal by the card reader. The system checks the information against its backlog and returns it to the reader. If the tag is in the system, the door will unlock. These sorts of systems also are used in hotel key cards, high-security areas, and more.

There are many kinds of RFID access systems. However, they all work based on this basic concept. This doesn’t mean there are no differences from system to system. Not every system is compatible with one another. For example, some systems use various levels of frequency bandwidth. Access control systems often use low-frequency (LF), high-frequency (HF), and ultra-high frequency (UHF) bandwidth. LF is defined as being between 120 and 1355 kHz. HF is between 3 and 30 MHz. UHF, meanwhile, is between 300 MHz and 3 GHz. [1]

Syrma’s Access Control Tags

The dependability and programming options of our NFC and RFID tags make them ideal for every security need. Our customizable near field communication (NFC) tags facilitate the convenience and security features of wireless NFC connectivity without the constraints of limited form factors. In addition to lightweight wristbands and key fobs, we offer a unique NFC tag with a corresponding QR code. NFC tags can also be used in tandem with our VeriSure product authentication software solution, allowing common NFC-supported smartphones to take the place of additional manual readers or other hardware.

Our RFID solutions for access control management come in the form of wristbands, ISO cards, clamshell cards, vehicle mount tags, and key fobs. This makes our tags ideal for every kind of access control system. Some RFID tags have waterproofing options for systems that are exposed to the elements. We also provide for tag printing, so you can label your tags as necessary. These RFID tags can be programmed for specific functions to make it easier to put them in your system. They come in HF and LF frequencies, with some options for UHF, as well.
