A counterfeit detector is a device that allows to differentiate legitimate banknotes from counterfeits, checking for this purpose through various technologies (ultraviolet, magnetic, infrared) different ticket security mechanisms. The counterfeit detector is highly demanded by all those who handle cash, since the increasing quality of fakes makes without your help it almost impossible to distinguish counterfeits from originals. Features security of euro banknotes notes issued by a National Bank as money, so-called Bank or paper money, banknotes include security features that serve as anti-counterfeiting elements. Some of these features are published by the issuing bank to allow the public quickly determine whether a banknote is genuine or not. Others not listed in official descriptions in order to preserve its security, even though many of them are known. Detector of counterfeits the counterfeits are increasingly sophisticated and difficult of detect, having reached the perfection of counterfeiting be so high that it is practically impossible to distinguish counterfeits from originals without a counterfeit detector. Another not inconsiderable advantage of the counterfeit detector is that the team who indicates the authenticity or falsity of the ticket, avoiding to be the person who handles cash responsible for making the decision, thus avoiding compromising situations. Various features, such as guarantee, durability, simplicity of handling or rapidity of validation, should be considered in a counterfeit detector but the main undoubtedly is reliability.
We must take into account that a counterfeit detector can produce two types of faults: false negative: taken by authentic a counterfeit. False positive: taken by fake a genuine banknote. Normally the counterfeit detector manufacturer the device undergoes tests for certification of the issuing bank. For euro, the ECB and the corresponding central banks of each State in the eurozone who is the certification and checking the percentage of detection. 100% Indicates that the counterfeit detector has passed all tests of detection of counterfeits. Counterfeit detector types there are several kinds of counterfeit detector according to the security mechanisms of the ticket checking, detecting their absence: counterfeit detector pen: a stroke on the ticket with the marker, is performed if black pint is false and if it paints yellow is authentic.
UV counterfeit detector: checked only ultraviolet markings. With ultraviolet and magnetic sensors counterfeit detector: Verify magnetic inks, ultraviolet marks and metallic filament. With ultraviolet, magnetic technology and infrared counterfeit detector: detects counterfeit notes by UV, magnetism, metallic thread, and infrared. Some counterfeit detector models include very convenient, such as additional features: currency counter.
I.e. in silence! We must remember that our information is floating in the air and all, we and also the neighbours have right and access to the same air. It is important to bear in mind, also, that waves of WIFI, are scattered in a radius of about 50 meters and 100 meters. This will depend on the obstacles and interference see loss of signal in WIFI and WIFI standard that we are using for the connection. The spread will have one wider scope in the very near future with new WIFI IEEE 802. 11n. For all this, and a Despite the convenience that represents arriving at an airport or a hotel, to be able to read our emails, connect to the Organization’s network and our banking transactions, it will have to be taken several security measures and understand all so quiet but as real threats to us be submitted to connect via wireless (wireless). 4.
Measures of security for a wireless WIFI network as a WiFi wireless network communication can be realized and the traffic can be captured and analyzed by anyone who is within range of the RF waves, will be essential to encrypt information, to strengthen security and avoid make it easily readable for any intruder. To encrypt the information in a wireless network, there are 3 methods that are widely described in the free course of WIFI wireless networks. These are: WEP: it is the weakest of all and try to avoid it. WPA: It is stronger than WEP and currently is the more used, many times due to limitations of equipment and others due to lack of knowledge of the WPA2 user: it is the strongest and the most recommended, but in many cases there is with computers that support it. The old WIFI equipment are not suitable for this type of cryptographic calculations. In addition, to avoid that hacker or hackers entering our server silently, through the WIFI network, it is very important to authenticate and authorize users by means of a RADIUS server and EAP protocols, as required by the standard IEEE 802.
1 x. The EAP protocols most used to authenticate users of WIFI are: EAP-LEAP EAP-TLS EAP-TTLS EAP – PEAP a broader explanation of authentication and authorization of users through RADIUS and the demands of the 802.1 x standard servers can be found in the White Paper basic concepts of security in wireless networks WIFI and several chapters of the free course of wireless networks WIFI: authentication/802. 1 x, RADIUS server, EAP authentication and Suplicantes in the second part of this article will discuss the most common threats that lurk permanently to users of WIFI and the precautions that must be taken to mitigate the insecurity. The author of this article, Eduardo Tabacman, is engineer network wireless WIFI and computer security specialist. On site which is editor and founder, will find many entertaining articles similar to this about computer viruses, network security and Wireless networks. In the free course on WIFI networks, you will discover numerous secrets that aren’t in any book in Spanish. Subscribe free to our newsletter at, and you will receive a gift video.
Single roll crusher is actually part of the structure of the jaw crusher and crusher combined roll, and thus has the characteristics of both aircraft types, also known as jaw roll crusher, crusher. Single-roll crusher having a large feed ports, the other surface of the roller equipped with different rack the rack bulk material when the bulk material feed higher crushing, vise, and splitting and shock method be broken, and then drops downward, its progress is crushed to the required size by the smaller teeth. In a crusher there are pre-crushed zone and the secondary crushing zone, and therefore can be used for the coarse material crushed, and crushing the relatively large, up to 15. The broken material block by the teeth on the roller edge toggle and the take-away is mandatory discharge, crushed sticky material will not happen clogging.The crusher is widely used in mining, metallurgy, building materials, road, railway, water conservancy and chemical industry and many other sectors. Single roll crusher is designed for crushing medium hard or soft materials, such as lime right, hard glue and coal. When the material is relatively sticky wet (such as those containing limestone, etc.), it is a crushing effect than using a jaw crusher and cone crusher are good, especially compared to a broken flake glue the material, with jaw or cone crusher both in performance and body compact square strengths. The specifications of the single-roll crusher is represented by the diameter and length of the roller.
In order to further joint with the market and meet the requirement of customer, Hongxing has paid close attention to the update information of mining industry. Today we will discuss the three major developing trends in the crusher; following is the opinions that Hongxing machinery provided:as the professional manufacturer of complete sets of mining machinery, such as rotary kiln, Henan Hongxing is always doing the best in products and service. 1.

Ecological waterproof: Pallets plastic not spoil with water, in fact can be cleaned with water without forming any type of mold. Dimensional stability: the productive system by pressure into a mold injection gives them totally repetitive dimensions, so the fit is much higher, saving transport costs. Rfid labeling: Labelling by rfid radio frequency system, opens a huge range of possibilities in the management of goods transported in these types of plastic pallets. Current injection with the IML system technology in mould labeling, allows the absolute integration of the label rfid in the plastic. Lightness: Plastic pallets are lighter than wood, and therefore produce fewer injuries during its handling. Ease of cleaning hygienic: plastic pallets are more resistant to the adhesion of different to the own plastic substances. Stable mechanical properties in all situations, all units are exactly equally resistant. In addition these conditions are excellent, if we compare two pallets of equal weight, one plastic and one of wood, the latter is much weaker, tensile, compression, bending, etc higher life: plastic pallets are much more long-lived, since they are resistant to external agents both physical and chemical. Safety at work: the pallets of wood produce wounds, mainly due to the chips and wood dust emitted by, something that does not happen with plastic pallets.
