Marked cards are playing cards with special markings that aid poker players and magicians recognize the suit and value of the hand. The markings are only observed by cameras and are not visible to the naked eyes.
IR Copag marked poker cards are more secure than cheating devices like luminous contact lenses or lenses that emit light. They are only visible by a special infrared camera.
Infrared ink
Invisible ink technology is highly advanced and can even be used to create marks on cards. It can be printed with markings on the back and sides of a card with the aid of top-of-the-line printers. In order to read the marks you’ll need additional devices. This can result in the process becoming more costly, but it is worth the investment. Additionally, the process of invisible ink is stable and can last for a long time.
An ink formulation that is completely invisible to the human eye, but readable by 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. This ink can be utilized for offset printing, printers using lithography in flexographic printing, offset printing, and the rotogravure process.
IR inks are functional inks which selectively transmit infrared light as well as blocking visible and ultraviolet light. They are detectable by a professional LS108A or LS108D Linshang lens transmission measurement. This instrument can determine the transmittance of IR ink at 550nm or 840nm. It’s highly effective in detecting counterfeit pen cartridges and other items that use invisible inks. The device can be used to gauge the amount of ink in a pen. The most effective IR pens should have a low reflectance, and the highest transmission at 840nm.
Contact lenses infrared
Infrared card technology of today uses an invisible ink visible at only 900 nanometers in the light spectrum. The card’s user is able to read the mark on the card without drawing attention from the other players. Cheaters are wearing IR lenses to prevent being detected. They are able to detect and read the marks from an extended distance. These lenses are often used with designer glasses or sunglasses to avoid the attention of fashion police.
Sandwich Technology is used in these contacts. This lets the filter remain inserted within the interlayer and makes sure that the eyes of the user are not directly touching the filter. They are safe for anyone with any color of eyes and won’t alter your pupil’s color. They’re comfortable and wearable all day long.
The prototype was constructed with a wireless illumination device inside soft contact lens. The device was constructed by chemically crosslinking the silicone Elastomer solution to create an NIR/far red LED, an ASIC chip and a transmitter. The ASIC chip was attached to a custom-designed power amplifier, which wirelessly transferred electrical power to the far red/NIR light to emit light. The transmitter was mounted onto PET film that was then passivated by Parylene. The infrared sensors triggered the lens’ electronics by transmitting a signal of 600 Hz. This created an AC voltage on the electrodes within the LC layer.
Infrared camera
In contrast to night vision, which makes use of light to create images, infrared technology relies on heat. It can be used for various purposes for industrial, medical and security applications. Firefighters make use of IR imaging to locate people in smokey conditions and to pinpoint hotspots. This increases the safety and effectiveness. It is also used to identify gaps in insulation and air leaks in HVAC, ventilation and air conditioning systems. It helps reduce energy consumption and enhances efficiency of HVAC systems.
Infrared cameras utilize a photon-converting detector, usually Indium Gallium Assenide (or microbolometer) which measures the low-frequency electromagnetic radiation which is felt as heat. This data is converted into a digital picture. This image can be viewed on the camera’s display or transmitted to an electronic device for analysis and report. The majority of top thermal cameras have software that converts the data into visual representation of temperature fluctuations, which typically appears as an array of colors. Warmer areas are shown in red while cooler regions are displayed in blue.
Documentation is required by most IR inspections as well as businesses. Therefore, it is essential to employ an infrared scanning device which produces clear and precise reports. There are a variety of manufacturers who offer software for free to create reports and review images. More advanced software can be purchased for in-depth images or for customizing reports.
Infrared sensor
Infrared sensors can be used to detect a variety of security applications including motion detection. When the sensor detects a change in the infrared radiation generated by the object, it sends an electrical signal to a computer embedded, which sets off an alarm. It can also trigger other security systems like automatic doors and video recording. It is dependent on the system being used, an infrared sensor could detect the presence of a person and trigger a hands-free door opening mechanism.
Infrared sensors are commonly employed in motion-based detection. They make use of a pair of parts that resemble pyroelectrics to detect infrared energy and create the electronic signal when an object comes within their boundaries. The sensors can also be used to determine distances using the time it takes for IR light to bounce back.
Although these sensors are powerful tools for security buildings, they are vulnerable to certain environmental variables. Sensors are susceptible to being confused by sudden temperature changes and high humidity, resulting in false alarms. Dust and dirt can also collect over time on the lens of the sensor, altering its ability to recognize infrared light.
It is essential to consider the setting and environment in which an infrared detector is placed. It is also recommended to conduct professional maintenance and inspections on infrared detectors every now and then. This will help ensure that the device functions properly and that it’s accurately detecting objects.
