Marked Card are playing cards with special markings to aid poker players and magicians identify the value and suit of a specific hand. The markings are not visible to the naked eye and only read by a special camera.
IR Copag marked poker cards are more secure than cheating devices such as luminous contact lenses or glasses with luminous markers. Only an infrared camera can recognize them.
Infrared ink
The technology behind invisible ink is very modern and can be used to mark playing cards. High-end printers mark marks on the back and sides of cards. To read the markings, you’ll require additional devices. The process is expensive but worth it. Additionally, the process of invisible ink is robust and can last for many years.
An ink formulation that is completely invisible to human eyes, but visible 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. It is ideal for printing by offset, lithographic, flexographic and Rotogravure printing methods.
IR inks are inks that function that transmit light infrared while blocking ultraviolet and visible light. A professional lens transmission meter LS108A/LS108D can detect the inks. This device detects the transmission of IR inks between 550nm and 840nm. It’s helpful for finding fake pens, well as other products using invisible inks. It can also help you determine the amount of ink that is contained in the pen by analyzing its reflectivity. The most efficient IR inks must be low in reflectance as well as an extremely high transmittance of 840nm.
Contact lenses that incorporate infrared technology
Modern infrared marked cards employ invisible ink that is visible only at 900 nanometers of the spectrum of light. This lets the user read the marks without drawing unfavorable attention from others. Cheaters wear IR lenses to prevent being detected. They are able to see and read the markings from at a distance. They are usually fitted with designer-style glasses or sunglasses to avoid the attention of fashion police.
Sandwich Technology is used in these contacts. This lets the filter stay inserted within the interlayer and keeps the eyes of the user from directly touching the filter. This ensures that they are safe for all types of eye color and doesn’t change the colour of your pupils. They’re comfortable and wearable throughout the day.
The prototype was constructed with a wireless LED placed inside the form of a soft contact lens. The device was created by chemically crosslinking the silicone elastomer to create a capsulation of an ASIC chip and a far red/NIR LED. The ASIC chip is then connected to a customized power amplifier that wirelessly transmits electric power to the far the red/NIR led to produce light. The transmitter coil was positioned on a PET film that was then passivated by Parylene. The infrared sensor activated the lens’s electronics by sending a 600 Hz signal. This caused an AC voltage to the electrodes of the LC layer.
Infrared camera
Contrary to night vision, that uses light to produce images, infrared technology depends on heat. It is utilized to serve a variety of functions, such as in medical, industrial and security applications. Infrared imaging is a crucial tool for firefighters to locate people in smoke-filled environments and spot hotspots. This improves safety and efficiency. It is also used to identify gaps in insulation and air leaks in heating, ventilation, and air conditioning systems. It aids in reducing energy consumption and enhances efficiency of HVAC systems.
Infrared cameras employ a photon-converting detector, typically Indium Gallium Assenide (or microbolometer), to measure the low-frequency electromagnetic radiation that is absorbed as heat. This data is converted into a digital picture. The image can either be displayed on the camera’s screen or sent to a computer where it will be analysed and reported. Most of the leading thermal cameras come with software that transforms the information into visual representation of temperature changes, which typically appears as a color matrix. Red is used to represent warmer regions, while blue is used for cooler areas.
Documentation is required by the majority of IR inspections and companies. This is why it is crucial to invest in a high-quality infrared camera to produce crisp, precise reports. A lot of manufacturers offer the software free for basic analysis and report creation as well as more sophisticated software is available for more in-depth imaging and report customization.
Infrared sensor
The technology that makes up an infrared detector is used in a variety of security applications, including motion detection. The sensor sends out a signal to an embedded computer whenever it detects any changes in the infrared emission of an object. The alarm is then activated. Other security systems are also triggered, including automatic doors and videos. It is dependent on the system being used, an infrared sensor can also detect the presence of a person and trigger a hands-free door opening mechanism.
Infrared sensors can be used for motion-based detection. They utilize a pair of parts that resemble pyroelectrics to detect infrared and produce an electronic signal when the object is within their zone of. They also can determine the distance of an object from the sensor through measuring the amount of time it takes the IR energy to bounce back.
Sensors are a fantastic security tool, but they are susceptible to environmental elements. For example, sudden temperature changes or excessive humidity can cause confusion to the sensor and cause false alarms. Dust and dirt can also get accumulated over time on sensor’s lens, affecting its ability to detect infrared light.
It is important to consider the surrounding environment and where an infrared detector will be installed. It’s also advisable to perform professional maintenance and inspections on infrared sensors each and every now and. This will ensure that the device is working correctly and is detecting an object correctly.
