IC Industry news

Vulnerability has been broken in your hands the IC card card also safe?

"I heard someone the IC card, password cracking, and I use the Beijing Municipal Administration and Communications Card still safe?" Recently, Ms. Wang to the newspaper readers to call. IC card is the most commonly used in real life as a micro-payment card. And bank card IC card different is that there is no magnetic strip on the back of its internal information from a memory chip and the coils. Users do not need to enter a password when used, is very convenient. IC card, there are two main categories: one non-contact, and the chip card, such as we use the bus card, access cards, parking cards. Users only need to make the card from the IC card in a certain range of the receiver, the cards information can be passed to the receiver. The contact type IC card chip is exposed outside the card, the user must put the card into the receiver can ...

Vulnerability of Chinas solar industry, mainly due to "two out"

Solar energy enterprises in China, "two out", the upstream and downstream companies in China are not subject to control, is the main reason for their industry is too fragile. In the entire solar energy industry chain, the upstream and downstream users of silicon raw materials in foreign countries, only the middle of processing chain in the country. Once the upstream and downstream fluctuations, the middle part of the natural squeezing the most vulnerable. At present, the domestic solar companies upstream silicon raw material prices plunge enterprises, and most of the domestic enterprises in the high prices of raw materials, through contracts and orders for the supply lock, and once the price dips upstream, downstream trade is bound to affect prices in a period of time They use high-priced raw materials to produce low-priced products, th...

VxI Power of 170W switching power supply for low-power system

VxI Power has introduced the 170W switching power supply designed for a single backup battery applications, low-power systems for backup power. The Oracle II-170 backup power supply output voltage is 12V or 24V two types of products, mainly for emergency applications, such as FireWire panel (fire panels), security systems and process control equipment. Oracle II-170 main output for standby power supply to the load, times the output for an external battery. Failure in the main output, the battery can be fed through the internal diodes to the load before. The power supply has anti-overload, short circuit, reverse polarity, overvoltage and undervoltage functions. Four LED are used to indicate input failure, charger failure, battery low and battery fault, no-voltage relay board can be provided as an option. VxI Power Companys power supply is...
