This article will explore the advantages of using mobile phones as keys to open doors, especially the unique functions of QR code access control, and analyze how it can replace traditional card access control.

 

 

1. Disadvantages of traditional card access control

Although the traditional card access control system has been widely used in the past few decades, it has certain limitations in many aspects:

① Card loss or damage: When using the card system, if the card is lost or damaged, the user needs to reapply, make, and activate a new card, which is not only cumbersome but also increases the management cost.

② Susceptible to duplication: If the traditional access control card is not encrypted, it is easy to copy, which brings security risks.

③ Inconvenient management: Traditional access control systems often require manual management or a local hardware system to set permissions, which is inefficient for places that need to frequently adjust access rights.

④ Poor user experience: You need to carry a card or induction card every time you use it, and the user may be unable to enter due to forgetting, damage, or loss of the card.

 

Therefore, the smartphone access control system that replaces the traditional card access control has become an important innovation direction.

 

2. Use mobile phone as the key to open the door - the intelligent and convenient choice

The concept of using a mobile phone as the key to open the door is gradually becoming a trend, and its main advantages are reflected in the following aspects:

① Convenience

Users only need to turn on their mobile phones, use the QR code applet or dedicated APP on their mobile phones to generate a QR code for opening the door, and after background authorization, they can open the door by facing the scanning lens of the QR code access control device. Compared with traditional card swipe access control, mobile access control is more convenient to use, and there is no need to carry additional cards or sensing devices. Especially for users who carry smartphones at all times in modern life, mobile access control systems are obviously more suitable.

 

② Security

The QR code access control uses high-intensity encryption technology, which greatly enhances security. Each generated QR code is unique and time-limited, and can be controlled for a limited time and number of times, avoiding problems such as card duplication and loss that may occur in traditional card swiping methods. Even if the QR code is intercepted by a third party, it cannot be used maliciously due to its timeliness and single-use restrictions.

 

③ Flexibility and scalability

QR code access control not only supports one-to-one door opening operations but also can realize one-to-many or multi-person sharing modes according to specific needs. For example, administrators can generate multiple-use QR codes or time-limited QR codes through mobile apps to facilitate the allocation of temporary access rights. In addition, QR code access control can be seamlessly connected with the company's existing systems (such as visitors, smart properties, etc.), further improving the integration and scalability of the system.

④Reduce costs

The traditional card access control system requires the purchase and maintenance of sensing equipment, access control cards, and card management systems. The mobile access control system only needs to install a QR code access control all-in-one machine, and users only need to use their own mobile phones, which greatly reduces hardware investment and subsequent maintenance costs.

 

3. Secondary development support for overseas software developers
