Thanks for joining us at HowToAV I'm Chris and today we're taking a look at QR code technology in
access control - What is it? How it works and its benefits to the world of security and door entry.
Keyless and touch-free door entry and access control have seen an increasing
range of identification technologies being applied to devices and systems. Most recently
we're seeing an increasing use of QR codes in access control and door intercom devices. QR codes
or to give them their full name 'quick response codes' are similar to conventional barcodes but
have much more flexibility. They're also able to hold much more data they can hold up to 2
500 characters compared to a standard barcode limit of just 43 and therefore they're ideal
for links to long address urls. In the case of access control QR codes typically an entry system
will include pc software or a smartphone app which can generate a unique QR code
that can be set to allow access for a limited time period for example specific date of the week,
limited number of uses and entry limited to specific areas floors or zones of a building.
Once a QR code has been generated it can be sent directly to the recipient by email or message
for them to display on their smartphone device or print out if required. A QR code enabled access
control device will feature a scanner usually in the form of a built-in camera the user then simply
displays the received QR code from the smartphone or printout to the actor's control device which
then scans it to confirm access rights within the specified time or the usage criteria. So
what are the benefits of QR code technology being used in access control and door entry devices?
Keyless door entry is popular for its flexibility both for the user and the system administrator,
unique QR codes can quickly and easily be generated from a smartphone or pc app
and emailed to the user in any location around the world no physical key device is necessary.
Immediate access code generation an access QR code can be generated and distributed in
a matter of seconds for example - if a visitor arrives early and you're not home to let them in
or a package is delivered that you don't want to be left outside the front door, simply generate
a unique time limited entry QR code and send it to your visitor who can immediately scan the code
from their smartphone to unlock the door without having to wait for your return home.
Remote access management - high numbers of users and frequent temporary access
permissions requires a significant amount of system management and administration.
The ability to create and distribute access QR codes remotely from anywhere in the world allows
for a highly efficient system management solution. Flexible temporary access permissions -access QR
codes can be set for time limited and number of use limited entry ideal for one time only delivery
access or cleaning contractors for example who only require entry on a specific day of the week.
Contactless touch free door access - by scanning the QR code from your smartphone this supports
the trend for contactless door entry to help prevent the transmission of germs and viruses.
Reduced carbon footprint - QR codes effectively provide a virtual key removing any requirement
for physical keys, single-use plastics such as id cards or key fobs or printing on paper
thereby providing a notable reduction in overall environmental impact from your security system.
Cost effective - having a virtual key option reduces staff resource requirement, distribution
time and the requirement for physical key devices which significantly reduces ongoing costs.
So it's clear that QR codes are quickly becoming the contactless
temporary access solution of choice for door entry and access control systems.
