Marked cards are played cards with special markings that aid poker players and magicians to identify the values and suits of the hand. These markings are inaccessible to the naked eye and can only be read by a special camera.
IR Copag marked poker cards are more secure than other fraudulent devices, such as luminous contacts lenses or glasses with luminous markers. They are only visible with a specific infrared camera.
Infrared ink
Invisible ink technology is very sophisticated and can be utilized to mark playing cards. It is possible to print markings on the back and even sides of cards with the aid of high-end printers. To read the markings, you will also need other equipment. The process is costly but is well worth the cost. Furthermore, the process of invisible ink is very durable and lasts for a many years.
A new ink formulation that is not visible to the human eye, but easily readable with infrared light has been developed. 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 can be used for offset, lithographic, flexographic and the rotogravure printing technique.
IR inks are functional inks that selectively transmit infrared light while blocking visible and ultraviolet light. They can be detected by a professional LS108A or LS108D Linshang lens transmission meter. It can measure the transmittance of IR inks between 550nm to 840nm. It’s excellent in detecting fake pen and other products that use invisible inks. It can be used to gauge the quantity of ink contained in the pen. The most efficient IR inks need to be low in reflectance as well as a high transmittance at 840nm.
Contact lenses infrared
Modern infrared marked card systems use invisible inks that are visible only at 900 nanometers in the light spectrum. This allows the player to discern the markings, without drawing unfavorable attention from others. Cheaters wear IR lenses to avoid being caught. They can see and read the marks from the distance. They are usually fitted with designer-style glasses or sunglasses to avoid being the focus of fashion police.
Contact lenses use Sandwich Technology, which allows the filter to stay inserted into the inter layer and stop the eyes of the wearer from touching it directly. They are therefore suitable for all colors of eyes and doesn’t alter the color of your pupils. These glasses are comfortable and can be worn all day long.
The prototype was built by using a wireless light source in soft contact lens. The device was created by chemically crosslinking a silicon and elastomer solution, which encapsulated the far red/NIR LED an ASIC chip and a transmitter. The ASIC chip was attached to a custom-designed power amplifier, which wirelessly transferred electrical energy to the far-red/NIR LED to produce light. The transmitter coil was placed on the poly(ethylene terephthalate) (PET) film that was passedivated by Parylene C. The infrared receiver activated the lens’s electronics by transmitting an infrared frequency of 600 Hz that generated an AC voltage to the electrodes on the LC insert layer, thus changing the orientation of the lens with an electric field.
Infrared camera
Contrary to night vision, which uses light to create images, infrared technology is based on heat. It is utilized for many purposes like medical, industrial and security applications. The use of IR imaging is a vital tool used by firefighters to locate individuals in smoke-filled areas and pinpoint hotspots, which can increase safety and effectiveness. It can also be used to detect air leaks or insulation issues in heating, ventilation, and air conditioning systems. This helps to reduce energy consumption and enhance the efficiency of HVAC systems.
The infrared technology that powers an infrared camera consists of a photon converting detector (typically Indium Gallium Arsenide or microbolometer) that measures the low-frequency electromagnetic radiation felt as heat. It then converts it into digital images. This image can be viewed on the camera’s display or transmitted to computer for analysis or reporting. The majority of thermal cameras include software that converts the data into an image of temperature variations. This is usually displayed in a matrix of colors. The red color is utilized to highlight warmer areas and blue for cooler areas.
Many IR inspection programs and businesses require a method of recording the results of their activities. That’s why it’s important to have a top-quality infrared camera that can produce precise and clear reports. There are numerous manufacturers that offer software for free to create reports and analyze images. The more advanced software can be purchased for in-depth imaging or customizing reports.
Infrared sensor
The technology that makes up an infrared detector is used in a variety of security applications, such as motion detection. The sensor will send a signal to an embedded system when it detects any changes in the emission of infrared light from an object. This triggers an alarm. Other security systems are also alerted, like automatic doors and video recordings. The application that is used will determine the trigger. an infrared camera can detect the presence of a person and trigger a hand-free door opening mechanism.
Infrared sensors are typically employed for motion-based detection. They make use of two pyroelectric elements to sense infrared energy and produce an electronic signal each time an object is within their zone of. They also allow for measuring the distance an object is from the sensor by measuring the amount of time required for the IR energy to bounce back.
Sensors are a fantastic device to safeguard buildings, however they are vulnerable to environmental influences. Sensors can be confused by rapid temperature changes or high humidity, which can lead to false alarms. Also, dirt and dust collect over time on the sensor’s lens, affecting the ability of the sensor to detect infrared light.
It is important to think about the environment and location where an infrared detector is placed. It is also recommended to get a professional inspection and maintenance of an infrared sensor often. This will help ensure that the sensor is working well and that objects can be identified correctly.
