Marked cards are cards with special markings to help magicians and poker players identify the suit and value of a hand. These marks can only be seen by a camera and aren’t visible to naked eyes.
IR Copag marked poker cards are more secure than other cheating devices like luminous contact lenses or luminous markers glasses. Only an infrared-enabled device can recognize them.
Infrared ink
Invisible ink technology is sophisticated and could be used to mark cards. It can be printed with markings on the back or even sides of a card with the aid of top-of-the-line printers. To read the markings, you’ll also require other devices. This can make the process more expensive, but it is well worth the cost. Ink that is invisible is also able to last a long time.
A formulation of ink that is invisible to the human eye but accessible to 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. This ink is suitable to print offset, lithographic, flexographic and rotogravure printing techniques.
IR inks transmit infrared, while blocking ultraviolet and visible light. They are detectable by a professional LS108A or LS108D Linshang lens transmission meters. This device detects the transmission of IR ink between 550nm to 840nm. It is useful for finding fake pens, and other items that use invisible inks. It can also be used for measuring the amount of ink contained in the pen. The most efficient IR inks need to have low reflectance and a high transmittance at 840nm.
Contact lenses infrared
Modern infrared marked cards employ invisible ink that is visible only at 900 nanometers within the light spectrum. The card’s owner can read marks on the card and not draw the attention of other players. To avoid being caught, cheaters wear special IR contact lenses that permit they to see the markings and read them from the distance. These lenses are usually worn with sunglasses or glasses that look like designer frames to ensure that they are utilized without attracting the attention of the police.
Sandwich Technology is used in these contacts. This allows the filter to remain inside the interlayer, and keeps the eyes of the user from directly touching it. They are safe for all eye color and do not alter the color of your pupil. They’re comfortable and can be worn all day long.
The prototype was created using a wireless illumination device in soft contact lenses. The device was created by chemically crosslinking a silicone elastomer to make a capsule for an ASIC chip and a far-red/NIR LED. The ASIC chip was connected to a custom power amplifier that wirelessly transmitted electrical power to the far red/NIR light to produce light. The transmitter coil was placed on the poly(ethylene terephthalate) (PET) film that was passedivated with Parylene C. Infrared receivers activate the lens electronics by sending an infrared frequency of 600 Hz that caused an AC voltage to the electrodes on the LC insert layer, thus moving it around with an electric field.
Infrared camera
Unlike night vision, which uses light to create images, infrared technology relies on heat. It can be used in a variety of methods, including security, medical and industrial settings. Infrared imaging is a crucial device for firefighters to identify individuals in smoke-filled areas and spot hotspots. This can increase safety and effectiveness. It is also used to identify air leaks or insulation problems in HVAC, ventilation, and cooling systems. This will help to decrease energy consumption and enhance the efficiency of HVAC systems.
Infrared cameras utilize a photon-converting detector, usually Indium Gallium Assenide (or microbolometer) that measures low-frequency electromagnetic radiation which is felt as heat. This information is then converted into a digital picture. The image could be displayed on the camera’s screen or transmitted to a computer, which is then analysed and analyzed. The majority of top thermal cameras have software that can translate the data into visual representation of temperature changes, which is usually displayed as a color matrix. Warmer areas are shown in red, while cooler areas are shown in blue.
Many IR inspection programs and companies require a method of recording the results of their activities. This is why it’s vital to utilize a top-quality infrared camera that produces precise and clear reports. There are numerous manufacturers that provide free software to make reports and analyse images. The more advanced software can be purchased to get more detailed images or for customizing reports.
Infrared sensor
The technology that powers an infrared sensor is used in a variety of security applications, such as motion detection. When the sensor detects shift in the infrared radiation that is emitted by a particular object, it sends out an electrical signal to an embedded computer, which triggers an alarm. Other security systems may be activated, such as automatic doors and videos. Depending on the application, an infrared sensor can also detect the presence of a person and trigger a hand-free door opening mechanism.
Most commonly, infrared sensors are used for motion-based detection. They make use of an array of pyroelectric components to sense infrared energy and produce an electronic signal each time objects are within their distance. They can also be used to measure distances, by measuring the time it takes for IR light to bounce back.
Although these sensors are a powerful tool for securing structures, they are also susceptible to certain environmental variables. For example sudden temperature fluctuations or excessive humidity can cause confusion to the sensor and cause false alarms. Also, dirt and dust can accumulate on the sensor’s lens in time, which could hinder its ability to detect infrared radiation.
To overcome these limitations It’s crucial to take into consideration the place and the environment in which an infrared sensor will be installed. Additionally, it’s recommended to have professional inspection and maintenance performed on an infrared sensor every at least once a year. This will help ensure that the sensor operates well and that objects can be identified correctly.
