On top of redirecting to websites, what are other practical uses for QR Code? As the QR Code technology becomes more mature, many corporates are adopting the use of QR Code to improve quality of life. Indeed, the new technology brings a lot of convenience to us, for instance:

(1) QR Code Access Control System – Control access rights with QR Code in specific time and dates

(2) QR Pay – Simplify the payment process by scanning the QR Code for the payment interface

(3) QR Code verification – Confirm user identities for security 

QR Code Access Control System – Simplify visitor registration procedures

QR Code Access Control System makes use of scanning of QR Code to enter and exit designated premises. The system back-end admin can check individual access status and set QR Code to restrict access rights, so there is no need to manually process the entry and exit registration at the entrance and exits. 

How does it actually work? Admin can input visitor information to generate a QR Code and send the QR Code pattern (in PNG or JPG format) to visitors via instant messaging applications like email or WhatsApp, visitors can then use the code with the QR Code scanner at the entrance to enter the building. On the other hand, admin can also generate QR code with limited time to restrict the entry date and time, or the access rights for certain rooms within a flat, which is very helpful for security!

QR code access control application – hotel, hostels, youth hostels

When going on travelling or Staycation, we often book the rooms. Most of the rooms make use of access control cards (NFC cards), keys or password locks for the door. Access control cards and keys are easier to lose, and the password locks take relatively longer unlocking time. The use of QR Code controls visitor access permission in a faster and safer manner. 

Visitors just need to scan the QR Code, rooms and doors of facilities will be unlocked immediately within just a second, waiving all the time needed and HR needed for check-in and check-out. With the QR Code sent to the visitors in advance, they can enter the corresponding rooms at the designated time. 

QR code access control application: general office, working space, co-working space

Co-working space provides services and facilities  like individual offices, independent or shared desks, conference rooms, office equipment rental, etc. Most clients use access control cards to enter the booked offices, but when they lose the cards, temporary cards must be distributed instead. 

Managing members of different levels is another big issue, with different requests such as long-term rental, short-term rental, independent office, desk rental or shared desk rental and more. The existing HR management system wouldn’t be able to afford such an operation model in co-working spaces. 

QR code access control grants the right to visitors with just a QR Code, without requiring visitors to download mobile apps, nor hardwares such as access control cards or membership cards. Admin can also set the time and venue for specific QR codes to limit visiting duration and facilities, reducing the cost for reception while achieving the concept of ‘unmanned business’. 

To conclude, QR Code access control has the 3 main advantages: 

(i) Simple installation

There is no need to modify existing handles, locks and electronic magnetic locks on the facilities. You only need to install an IoT control panel and QR code scanner that connects to the system and manages the back-end admin panel. It acts as a more digital and high-tech access option on top of existing access control cards and passwords. 

 (ii) Remote control

QR Code is compatible with Wifi connection, that connects access control records with hardwares and cloud servers. It also enables the remote end to use the back-end or mobile app to lock with just a key, while instantly knowing the real-time opening and closing status of doors in different locations, which is more convenient for remote management. 

(iii) Back-end management

Whenever someone enters and exits, data like date, time, name, code and location, etc will all be stored in the back-end database. On one hand, it facilitates easier reporting and information management with a downloaded Excel; on the other hand,  it allows uploading existing visitor information. Data can be integrated and freely exported or imported, while status of hardwares can also be better monitored.  How is the IoT solution making us a smart office?Is the Smart Booking System applicable to your business?
