Most buildings provide visitors with smartcards to gain access to a building.
However many visitors forget or fail to return their access card when they leave the building.
This becomes expensive over time, leading some building owners to look at other less expensive solutions for visitor access control.
The challenge is to find something cheaper that can still be used with access control systems.
What are QR codes and where did they come from?
QR codes are 2D barcodes which were first created in Japan in 1994.
They can be printed onto something like a business card, displayed on a website, or sent via an email message.
The code holds data, for example, a unique number, that can be sent to the access control system
How do I use QR Codes in Access Control Systems?
Printed or electronic QR codes can replace smartcards or paper sign-in books.
The QR code is emailed, or sent via a Smartphone app to the visitor in advance of them arriving on site.
The visitor simply presents their QR code to an access control reader to gain access when they enter the building.
How do I produce a QR code?
QR codes are cheap and easy to produce, and can be generated by a range of low-cost or free software applications.
The code is then emailed or sent via smartphone app to the visitor.
What is needed to support QR Codes?
QR codes are read optically, and may therefore require an additional reader to be installed.
Some manufacturers are now producing readers that can combine RFID and QR Code into a single unit.
Adding QR Code readers alongside existing RFID readers will increase cost, but will pay for themselves over time.
What are the risks?
QR codes can be copied, so additional care needs to be made on how long the credential is valid for.
The authorisation matches the date and time of the planned visit to ensure that the credential cannot be used incorrectly.
Deploying turnstiles with anti-pass back will prevent a second person with a duplicate QR code gaining access.
