Today, a customer who has been working with us for two years asked this question.

UID card and Mifare Classic 1K card are two different types of smart cards, which differ in design and function:

Storage structure: Mifare Classic 1K card has 1KB of storage space, divided into 16 sectors, each sector contains 4 blocks, each block is 16 bytes. Block 0 of sector 0 usually contains the manufacturer UID code as the card identification code. UID card is a common copy card, which can repeatedly erase and write all sectors, but it may fail if the access control system has a firewall.

Security: Sector 0 of Mifare Classic 1K card cannot be modified, and other sectors can be repeatedly erased and written. It has 4 main permissions: read, write, increment, decrement, and 2 additional permissions: read and write control code, read and write A/B password. These permissions require the use of A or B password and operate under the constraints of the control code.

Use: Mifare Classic 1K card is usually used for access control cards, elevator cards, etc., while UID card may be used in some scenarios that do not require high security. The design of the Mifare Classic 1K card includes security considerations, such as using passwords to protect access to sectors.

Special types: There are different types of cloned cards, such as CUID, FUID, and UFUID, which provide different levels of security and features. For example, CUID cards can penetrate most firewalls, while UFUID cards become M1 cards after sealing the card, and UID cards if the card is not sealed.

UID cards

UID and BCC: Mifare Classic 1K cards, like other MIFARE cards, have a UID (Unique Identifier) and a BCC (Block Check Code). The BCC is a checksum of the UID, and if not configured correctly, it may cause the card to be undetectable, i.e. "bricked".

Modifiability: Some MIFARE cards, known as "Magic" cards, allow the manufacturer block to be modified, which is not allowed in the original card. However, if Block 0 is not configured correctly, the card may be "bricked", i.e. irreversibly damaged.

Technical cracking: Mifare Classic was cracked in 2008. If the KEY of any segment in the card is known, all KEYs can be obtained through simple brute force. But many cards used in formal occasions do not use the default key


Why do we need to install a 90-degree automatic gate opener? What are the advantages? Several new customers have recently asked the same question about automatic door openers.

here are three of the biggest advantages of a 90-degree automatic swing gate opener:

Enhanced Accessibility: A 90-degree automatic sliding gate opener provides a wider opening than traditional doors, allowing for easier access for people with disabilities, such as those in wheelchairs, as well as those pushing strollers or carrying bulky items. This can be especially beneficial in public spaces like hospitals, airports, and shopping centers.

Improved Safety: Automatic doors, including 90-degree openers, can help reduce the risk of accidents caused by manual doors. They eliminate the need for individuals to physically push or pull the door open, which can lead to slips, trips, and falls. Additionally, automatic doors can be equipped with sensors that detect the presence of people or objects in the doorway, helping to prevent collisions and injuries.

Increased Efficiency: In high-traffic areas, manual doors can create bottlenecks and slow down the flow of people. A 90-degree automatic door opener can help alleviate this issue by allowing for a smoother and more efficient traffic flow. This can be especially important in commercial settings, such as retail stores, where a fast and efficient customer experience is crucial. Additionally, automatic doors can be programmed to open and close at specific times, helping to conserve energy and reduce costs.

How do 90-degree automatic door openers differ from other types of door openers in terms of design and functionality?

90-degree gate opener system differentiates from other types of door openers in several ways, particularly in their design and functionality:

Opening Mechanism: The most obvious difference is the opening angle. A 90-degree automatic door opener swings the door open to a full 90-degree angle, unlike sliding door systems or revolving doors, which move differently.

Space Requirements: Due to the 90-degree swing, these openers require sufficient space on one side of the door for the door to open fully without obstruction. This contrasts with sliding door systems, which do not require additional lateral space.

Energy Efficiency: Some 90-degree automatic door openers are designed with energy-saving features, such as motion sensors that activate the door only when needed, reducing unnecessary energy consumption compared to continuously powered systems.

Integration with Security Systems: They can be integrated with access control systems for added security, allowing the door to open only for authorized individuals. This level of integration might vary with other door opener types.

Sensor Technology: 90-degree automatic door openers often utilize advanced sensor technology to detect the presence of people or objects, ensuring safe operation and preventing the door from hitting anything during its swing.

Aesthetics: The design of a 90-degree gate automatic opening system can be more streamlined and less obtrusive than other types, especially when considering the visibility and aesthetics of the mechanism.

Maintenance: The maintenance requirements for a 90-degree sliding automatic gate opener kit can differ from other types. For instance, hinged doors may require less maintenance than sliding or folding door systems, which have more moving parts.

Weather Resistance: Some models are designed to withstand various weather conditions, ensuring reliable operation even in adverse climates, which might be a consideration not as prevalent with indoor-only door systems.


Each type of swing gate operator is suited to different applications based on the specific needs of the building or space they are intended for. The choice of door opener will depend on factors such as available space, traffic flow, security requirements, and environmental conditions.

If there is a trip or power outage, it is generally caused by excessive power consumption, short circuit or wrong wiring, or improper settings.

Because the limit switch is disconnected when the door is opened, the control circuit is open and causes tripping. This is a protective function.


automatic swing door opener

The reason why the 90-degree automatic door opener suddenly tripped may be excessive power consumption. When the power consumption of a device or system exceeds the carrying capacity of the circuit or power supply, to protect the Door opener and power supply from damage, the automatic tripping mechanism will be triggered, thereby cutting off the power supply to prevent the device or system from being damaged due to overload. In this case, checking and reducing power consumption is an effective solution. In addition, ensuring that the carrying capacity of the power supply and circuit matches the actual power consumption of the equipment is also an important measure to prevent tripping.


3main reasons:

1. Circuit fault causes the electric door to trip

2. Switch fault causes electric door to trip

3. Electric door motor overload causes the trip
