Invisible Marked Cards

Marked cards are playing cards with special markings to assist players and magicians understand the worth and suit of a particular hand. These marks aren’t visible to the naked eye, and are only visible to a special camera.

IR Copag marked poker cards are more secure than cheating devices like luminous contact lenses or lenses that emit light. They can only be seen with a specific infrared camera.

Infrared ink

The technology behind invisible ink is modern and can be used for marking playing cards. It can be printed with markings on the back and the sides of a card using the aid of top-of-the-line printers. However, other equipment is also needed to read the marks. This can result in the process becoming costlier, but is worth the investment. The ink technology behind invisible can last a long time.

A formulation of ink that is indistinguishable to the human eye but is visible by infrared 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 to print offset or lithographic, flexographic, and the rotogravure printing technique.

IR inks transmit infrared light while blocking visible and ultraviolet light. They are detectable by an expert LS108A or LS108D Linshang lens transmission measurement. This device can detect the transmittance of IR ink at 550nm or 840nm, and it is extremely useful in detecting fake pens and other products that use invisible inks. This device can also be used to measure the amount of ink in the pen. The most effective IR pen models should have very low reflectance, and the highest transmission at the wavelength of 840nm.

Infrared contact lenses

Infrared cards of today use an invisible ink which is visible at only 900 nanometers in the light spectrum. The card’s user is able to read the marks on the card and not draw the attention of other players. To stay out of trouble cheaters wear IR contact lenses that enable players to read the markings and read them from the distance. These lenses are usually sported in glasses or sunglasses that look like designer frames, to ensure that they are used without drawing attention from the police.

The contacts utilize Sandwich Technology, which allows the filter to be placed within the interlayer to prevent the users’ eyes from contacting it directly. They’re safe for anyone with any color of eyes and won’t alter the color of your pupil. They are also very comfortable to wear and can be worn for extended periods of time.

The prototype was developed using a wireless lighting device that was embedded within a soft contact lens. The device was created by chemically crosslinking the silicone and elastomer solution, which encapsulated a far red/NIR LED, an ASIC chip and a transmitter. The ASIC chip was connected to a customized power amplifier that wirelessly transferred electrical power to the far red/NIR light for light emission. The transmitter coil was positioned onto PET film that had been passivated with Parylene. Infrared sensor stimulated the lens’ electronics sending a signal at 600 Hz. This created an AC voltage to the electrodes within the LC layer.

Infrared camera

Infrared is a heat-based technology and is different from night vision, that relies on light to produce images. It can be utilized to serve a variety of functions, such as in industrial, medical and security applications. Firefighters utilize IR imaging in order to locate people in smokey areas and identify hotspots. This enhances security and efficiency. It can also be utilized to detect problems with insulation and air leaks in heating, ventilation, and air conditioning systems. This can help reduce the use of energy and increase the efficiency of HVAC systems.

The technology behind an infrared camera consists of the photon-converting detector (typically Indium Gallium Arsenide or microbolometer) which detects the low-frequency electromagnetic radiation that is felt as heat, and then transforms it into an image that can be digitalized. The image can be displayed on the camera display or transmitted to computers for analysis and report. Many of the top thermal cameras offer software that transforms the information into visual representations of temperature variations. This is often displayed as a matrix of colors. Warmer regions are highlighted in red, while cooler areas are shown in blue.

Documentation is required by the majority of IR inspections and businesses. It is therefore essential to employ an infrared scanning device which produces clear and precise reports. A lot of manufacturers offer the software free for basic analysis and report generation while more advanced software is available for more detailed imaging and report customization.

Infrared sensor

Infrared sensors serve to perform a myriad of security purposes, including motion detection. The sensor will send a signal to the embedded system when it detects any change in the infrared emission of an object. This triggers the alarm. It can also trigger other security systems, including automatic doors and video recording. Infrared sensors can be used to detect the presence the person in question and activate an opening mechanism for doors that doesn’t require a key.

Infrared sensors are most commonly used for motion detection. can be employed for motion detection. They use a pair pyroelectric components to detect infrared and produce an electronic signal when the object is within their zone of. They can also determine the distance an object is from the sensor by measuring the time it takes for the IR energy to bounce back.

These sensors are an ideal tool to secure buildings but they can be susceptible to environmental influences. For example sudden temperature fluctuations or excessive humidity can cause confusion to the sensor and cause false alarms. The dirt and dust collect over time on the lens of the sensor, affecting the ability of the sensor to detect infrared light.

It is important to think about the surroundings and the location in which an infrared detector will be placed. Moreover, it’s advisable to have professional inspection and maintenance of an infrared device every once in a while. This will help ensure that the sensor is operating correctly and that the object can be identified correctly.
