The new normal post-COVID-19 includes the use of contactless technology to guarantee employee wellbeing. Although offices, factories, and retail stores have started opening and activity levels are returning to normal, signs, indicate that some aspects of the pandemic lifestyle are likely to remain in practice for some time. Companies have started to deploy access-control devices with RFID and NFC readers as a part of their physical security to ensure the health and safety of staff and visitors. Another interesting event happening in smart buildings is occupancy and space control-related analytics and solutions by end-users to look at how their staff and employees use their space. It’s estimated that the occupancy analytics market will reach $5.73B by 2024 at 21.5% CAGR .
NFC & RFID Access Control
RFID technology makes use of electromagnetic waves to capture and read transmitted data. Information is electronically stored on a tag attached to an object or a carrier. The tag’s chip gets activated when it’s brought near a reader and enables it to share the access information. Different types of NFC and RFID readers are used in access control applications.
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 robust and secure access control. Thus RFID becomes a favored choice for several uses such as supply chain, inventory, parking garage gate control, retail checkout lines, and even race timing aside from office management.
RFID Frequency Bandwidth
There are many kinds of RFID access systems, and not every system is compatible with one another; 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 is between 300 MHz and 3 GHz. RFID has a read range of 1
NFC Mobile Applications
The latest 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/tablets/laptop is swapped or tapped over the NFC reader, a communication channel is established over the air interface. Data transactions take place to authenticate the authority of the user to access the secured area, resources, or applications.
The technology is expected to grow to $34.9B by 2025 at a CAGR of 14.2%. NFC adoption will continue to grow as customer experiences have become more sophisticated and demand interactivity. The number of handsets shipped with NFC is expected to hit 5B by 2021 and likely to play an almost certain role in the future smart devices with more integrated functions in the areas of smart transportation, aviation industry, shipping, industry automation, etc.
