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

The walkie-talkie explosion in Lebanon has attracted global attention and profound reflection on the safety of communication equipment.




Several potential causes may have led to this tragic explosion in Lebanon. Firstly, experts speculate that the 2 way radios might have been internally rigged with explosive detonators. Modern communication devices typically house components such as batteries and circuit boards; if maliciously fitted with explosive devices, such as mini detonators, during manufacturing or supply chain processes, these devices could be remotely triggered upon receiving specific signals or meeting preset conditions, leading to explosions.


Secondly, issues with the walkie-talkie's battery could also be a cause of the explosion. Although modern battery manufacturing processes are relatively mature, lax quality control or design flaws can still lead to explosions due to overheating or short circuits. However, considering the scale and impact of this explosion, mere battery failure seems insufficient to account for the entire situation.




Furthermore, some analyses suggest that these communication devices might have been modified at the production level, with undetectable explosives implanted. Such actions could involve complex supply chain infiltration and exploitation of security vulnerabilities. If true, this not only exposes significant flaws in equipment manufacturers' supply chain management but also poses a serious challenge to global safety standards for communication devices.


In the meantime, the incident in Lebanon has also alerted global manufacturers to the importance of product safety. In contrast, the walkie-talkies produced by Juston Electronic Equipment Co., Ltd. strictly adhere to international safety standards and undergo rigorous quality control from design to production.


Stringent Factory Testing: Each walkie-talkie undergoes a series of safety and performance tests before leaving the factory to ensure the product's stability and safety under various conditions.

International Safety Certifications: Juston walkie-talkies have obtained international safety certifications such as CE, FCC, IC, and RoHS, signifying compliance with global safety standards.



Use of Safe Materials and Technology: Juston utilizes advanced materials and technology in the design and production process to ensure the safety and durability of its products.

Juston's walkie-talkies are widely used in various fields including public safety, logistics, and tourism, and their reliability and safety have been recognized by customers and verified by the market.

One day after thousands of pagers exploded across Lebanon, more explosions of handheld devices, including uhf handheld 2 way radio, mobile phones, laptops and even solar power cells, have killed at least 26 people and injured  more than 3000.

 

 

Reports on Wednesday of several blasts quickly spread on messaging apps with people sharing images of exploded walkie-talkies and residential buildings on fire.

 
Japan's Icom Inc., whose brand appears on long range walkie-talkie that exploded in Lebanon, said it halted production a decade ago of the model allegedly used in the attacks and is still investigating the situation.
 
Icom exported its IC-V82 2 way radios to regions including the Middle East until October 2014, when it stopped making and selling the devices, the Osaka-based company said in a statement Thursday. It has also halted production of the batteries needed to operate the main unit, it said.
 
Among the many outstanding questions is how explosive materials were planted in the devices. If the Icom walkie-talkies were first manufactured a decade ago, it’s possible they were modified well after sale to their original customers. The company can’t determine if the products are their own, it said.
 

The company said all its radios are manufactured at a factory in Wakayama Prefecture, adding that it follows safety protocols outlined by government regulations and does not outsource production overseas.

 

 

Given that photographs of the devices show severe damage around the battery compartment, the batteries may have been modified with explosives after procurement, Icom director Yoshiki Enomoto was quoted as saying in a Kyodo report.

 
The detonations of everyday electronics may herald a new type of terrorism, according to Mitsuru Fukuda, professor of risk management at Nihon University. "This may increase pressure on companies to expand risk oversight of their supply chains” to include distribution and delivery, he said.


In the face of emergencies, the safety performance of communication equipment is crucial. JUSTON is well aware of this and always adheres to the design philosophy of "safe&reliable, creating excellent quality," committed to developing products that can withstand the test of extreme conditions. Our communication equipment has excellent impact resistance and durability, ensuring normal operation even in hazardous environments.
