Marked Cards are cards with special markings that help players and magicians identify the value and suit of a particular hand. These marks can only be observed by cameras and aren’t visible to naked eye.
IR Copag marked cards are more secure than other cheating poker tools such as luminous ink contact lenses or luminescent marker glasses. Only an infrared-enabled device can see these cards.
Infrared ink
Invisible ink technology is extremely advanced and is even used to create marks on cards. Printers with high-end capabilities can mark the back and sides of cards. But, other devices are also needed to read the marks. This can result in the process becoming costlier, but is worth the expense. Additionally, the technology of invisible ink is stable and can last for longer.
A new ink formulation that is not visible to the human eye but easily readable with infrared light has recently 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. The ink is suitable to print offset, lithographic, flexographic and Rotogravure printing techniques.
IR inks are functional inks that transmit light infrared as well as blocking visible and ultraviolet light. A professional LS108A/LS108D lens transmission meter will detect these inks. It can measure the transmittance of IR inks at 550nm and 840nm. It’s extremely useful in detecting fake pen cartridges and other items that utilize invisible inks. It can also help you find out the amount of ink in the pen by analyzing its reflectivity. The most effective IR inks need to have a low reflectance and the highest transmittance, which is 840nm.
Contact lenses that incorporate infrared technology
Modern infrared marked cards utilize invisible ink that is visible only at 900 nanometers on the spectrum of light. This allows the player to see the markings and not draw negative attention from other players. Cheaters wear IR lenses to prevent being caught. They are able to see and read the markings from at a distance. The lenses are typically worn with designer glasses or sunglasses to avoid attracting the attention of the fashion police.
These contact lenses utilize Sandwich Technology, which allows the filter to be inserted within the interlayer to stop the eyes of the wearer from touching the filter directly. They are safe for all colour of eye and do not alter the color of your pupil. They’re also very comfortable to wear and are able to be worn for extended periods of time.
The prototype was built with a wireless LED embedded in an optical contact lens that is soft. The device was constructed by chemically crosslinking the silicone elastomer to make a capsule for an ASIC chip as well as a far-red/NIR LED. The ASIC chip was then attached to a custom-designed power amplifier, which wirelessly transmitted electrical power to the far-red/NIR LED for light emission. The transmitter coil was placed on a poly(ethylene Terephthalate) (PET) film that was passedivated by Parylene C. The infrared receiver triggered the lens electronics through transmission of an infrared pulse at 600 Hz that caused an AC voltage to the electrodes of the LC insert layer, thus moving it around with an electric field.
Infrared camera
Unlike night vision, that uses light to produce images, infrared technology is based on heat. It is used for a number of purposes for medical, industrial and security applications. Infrared imaging is a crucial tool for firefighters to locate individuals in smoke-filled areas and pinpoint hotspots, which improves safety and efficiency. This is a great tool to spot air leaks or insulation issues in HVAC, ventilation and air conditioning systems. It aids in reducing energy consumption and increases the efficiency of HVAC systems.
Infrared cameras use a photon-converting detector, commonly Indium Gallium Assenide (or microbolometer) that measures low-frequency electromagnetic radiation which is absorbed as heat. This information is then converted into a digital picture. The image could be displayed on the camera’s LCD or transmitted to a computer which is then analysed and reported. The majority of thermal cameras include software that converts the data into an image of temperature fluctuations. The image is typically displayed in a matrix of shades. The red color is utilized to highlight warmer areas and blue for cooler areas.
The majority of IR inspection and business programs require a method to record the outcomes of their work. This is why it’s crucial to invest in a high-quality infrared camera that can produce precise and clear reports. A lot of manufacturers offer free software that can be used for basic image analysis and report creation and more sophisticated software is available for more detailed imaging and customizing reports.
Infrared sensor
The technology that powers an infrared sensor is utilized in a range of security applications, such as motion detection. If the sensor detects a change in the infrared radiation produced by a object, it broadcasts an electrical signal to a computer embedded, which causes an alarm. The sensor can also trigger other security systems like automatic doors and video recording. It is dependent on the system being used, an infrared camera can detect the presence of a person and trigger a hand-free opening mechanism.
Infrared sensors are typically employed in motion-based detection. They employ a pair of pyroelectric components to detect infrared radiation and emit an electronic signal if objects enter their range. They also allow for measuring the distance an object is from the sensor through measuring the amount of time it takes the IR energy to bounce back.
While these sensors are an effective tool to secure buildings, they are susceptible to environmental conditions. For instance, sudden temperature changes or extreme humidity could confuse the sensor and trigger false alarms. In addition, dirt and dust can accumulate on the lens of the sensor over time, and this could hinder its ability to detect infrared radiation.
To overcome these issues It’s crucial to take into consideration the area and surroundings in which the infrared sensor will be placed. Additionally, it’s recommended to hire a professional for inspection and maintenance of an infrared device every once in a while. This will ensure that the device is functioning properly and that it’s accurately detecting objects.
