Marked Cards are cards that have special markings to help poker players and magicians understand the values and suits of a specific hand. These marks aren’t visible to the naked eye, and can only be seen by a special camera.
IR Copag marked poker cards are more secure than other fraudulent devices, such as luminous contacts lenses or lenses that emit light. Only a special infrared device can recognize them.
Infrared ink
Invisible ink technology is sophisticated and is able to be used for marking playing cards. It is possible to print marks on the back, and even sides of cards with the aid of high-end printers. In order to read the marks, you’ll require additional devices. This makes the process more expensive, but it is worth the expense. Furthermore, the process of invisible ink is very stable and can last for many years.
A formulation of ink that is not visible to human eyes, but can be seen through infrared light has been created. The ink is based on silicon(IV) 2,3-naphthalocyanine bis(trihexylsilyloxide), which has strong absorbance in the IR and excellent transmitting characteristics in the visible. It is ideal to print offset, lithographic, flexographic and Rotogravure printing techniques.
IR inks transmit infrared, while blocking ultraviolet and visible light. They can be detected by a professional LS108A or LS108D Linshang lens transmission meters. This device can detect the transmission of IR inks at 550nm and 840nm, and it is very useful in detecting counterfeit pen and other products which use invisible inks. Additionally, it allows you to determine the quantity of ink that is contained in the pen through measuring its reflectivity. The top IR inks need to have a low reflectance and the highest transmittance, which is 840nm.
Contact lenses that incorporate infrared technology
Infrared chips of today employ an invisible ink that is visible at just 900 nanometers in the light spectrum. The card’s user is able to read the marks on the card and not draw the attention of other players. To stay out of trouble cheaters wear IR contact lenses that enable them to see the markings and read them at the distance. They are typically worn with sunglasses or glasses that look like designer frames to ensure that they are employed without attracting attention from the police.
These contact lenses utilize Sandwich Technology, which allows the filter to stay inserted within the interlayer to prevent the users’ eyes from touching it directly. They’re safe for every colour of eye and do not alter the color of your pupil. These glasses are comfortable and are suitable for wearing throughout the day.
The prototype was constructed using a wireless lighting device that was embedded within the form of a soft contact lens. The device was fabricated by chemically crosslinking a silicone elastomer solution to encapsulate a far red/NIR LED, an ASIC chip and a transmitter. The ASIC chip was then connected to a customized power amplifier that wirelessly transferred electrical power to the far red/NIR LED for light emission. The transmitter coil was mounted on a poly(ethylene terephthalate) (PET) film, which was then passivated by Parylene C. The infrared receiver triggered the lens’s electronics by transmitting the infrared signal at 600 Hz that caused an AC voltage to the electrodes on the LC insert layer, thereby shifting it by an electric field.
Infrared camera
Infrared is a heat-based technology, unlike night vision that relies on light to produce images. It is used in a variety of ways, including medical, security industrial, and security applications. Firefighters use IR imaging to identify people who are in smoky surroundings and locate hotspots. This enhances the safety and effectiveness. It can also be used to locate the presence of air leaks as well as insulation deficiencies in heating, ventilation, and air conditioning systems. It assists in reducing energy usage and increases the efficiency of HVAC systems.
The infrared technology that powers an infrared camera consists of an image-converting detector (typically Indium Gallium Arsenide or microbolometer) which detects the low-frequency electromagnetic radiation felt as heat. It then converts it into an image digital. The image is displayed on the camera display or transmitted to a computer for analysis and report. The majority of thermal cameras include software that converts the information into an image of temperature variations. The image is typically displayed in a matrix of colours. The red color is utilized to highlight warmer regions, while blue is used for cooler ones.
Documentation is required by most IR inspections and business. It is therefore crucial to have an infrared scanner that creates clear and precise reports. There are many manufacturers that offer software for free to create reports and analyze images. Advanced software can be purchased to get more detailed image analysis or to customize reports.
Infrared sensor
The technology behind an infrared sensor is used in a variety of security-related applications, including motion detection. The sensor will send a signal to the embedded computer when it detects a change in the emission of infrared light from an object. This triggers an alarm. Other security systems can be activated, such as automatic doors and video recordings. Infrared sensors may be used to detect the presence someone and trigger the door opening mechanism, which doesn’t require keys.
The majority of the time, infrared sensors are used for motion-based detection. These sensors use the pyroelectric elements to sense infrared energy and produce an electronic signal each time an object is within their range. They also can determine the distance of an object from the sensor by measuring the amount of time it takes the IR energy to bounce back.
These sensors are an ideal tool to secure buildings but they are also susceptible to environmental elements. Sensors are susceptible to being confused by abrupt temperature fluctuations or extreme humidity, resulting in false alarms. Dust and dirt can also get accumulated over time on lens of the sensor, altering its ability to detect infrared light.
To overcome these issues It is important to think about the location and environment where an infrared detector will be installed. Moreover, it’s advisable to have professional examination and maintenance for an infrared sensor every at least once a year. This will ensure that the sensor functions well and that objects can be detected correctly.
