Marked cards are playing cards with special markings that aid poker players and magicians recognize the suits and worth of a hand. These marks aren’t visible to the naked eye, and are only visible to a special camera.
IR Copag marked cards are more secure than other cheating poker tools such as luminous ink contact lenses or markers with luminous lenses. They can only be viewed by a special infrared camera.
Infrared ink
Invisible ink technology is advanced and is even used to create marks on cards. It is possible to print markings on the back or even sides of cards with the aid of high-end printers. However, other equipment is also needed to read the marks. This can result in the process becoming costlier, but is worth the expense. In addition, the technology of invisible ink is reliable and can last for longer.
A new ink formulation that is not visible to human eyes, but easily readable with 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. The ink can be used for offset or lithographic, flexographic, and rotogravure printing techniques.
IR inks are inks that function which selectively transmit infrared light as well as blocking visible and ultraviolet light. A professional LS108A/LS108D transmission meter can detect the inks. The device can detect the transmission of IR ink between 550nm to 840nm. It’s useful in finding fake pens, well as other products using invisible inks. It also allows you to find out the quantity of ink contained in a pen by measuring its reflectivity. The top IR pen should have a extremely low reflectance and an excellent transmission of 840nm.
Infrared contact lenses
Modern infrared marked cards use invisible ink which is visible only at 900 nanometers of the light spectrum. This lets the user read the markings without drawing the attention of other players. Cheaters are wearing IR lenses to avoid being detected. They are able to see and read the marks from a distance. The lenses are typically fitted with designer-style glasses or sunglasses to avoid the attention of the fashion police.
Contact lenses use Sandwich Technology, which allows the filter to remain inserted within the interlayer to prevent the users’ eyes from touching the filter directly. They are safe for all eyes and doesn’t alter the color of your pupils. They are also very comfortable to wear and can be worn for prolonged periods of time.
The prototype was built by using a light source wireless integrated into soft contact lenses. The device was made using chemically crosslinking silicone to form a shell around an ASIC chip as well as a far-red/NIR LED. The ASIC chip was then connected to a customized power amplifier that wirelessly transferred electrical power to the far red/NIR LED for light emission. The transmitter coil was mounted on a poly(ethylene Terephthalate) (PET) film that was passivated by Parylene C. The infrared detector triggered the lens’s electronics by transmitting a 600 Hz infrared signal which triggered an AC voltage to the electrodes on the LC insert layer, thus changing the orientation of the lens with an electric field.
Infrared camera
As opposed to night vision that uses light to produce images, infrared technology is based on heat. It can be used in a variety of methods, including medical, security, and industrial applications. Firefighters employ IR imaging to locate individuals in smoky areas and identify hotspots. This enhances security and efficiency. It is also utilized to detect problems with insulation and air leaks in ventilation, heating, and air conditioning systems. It assists in reducing energy usage and boosts the efficiency of HVAC systems.
Infrared cameras make use of a photon converting detector, usually Indium Gallium Assenide (or microbolometer), to measure the low-frequency electromagnetic radiation which is absorbed as heat. This information is then transformed into a digital image. The image may be displayed on the camera’s display or transmitted to a computer, which is then analysed and reported. Most thermal cameras have software that transforms the data into a picture of temperature fluctuations. The image is typically displayed in a matrix of shades. The warmer areas are displayed in red while cooler regions are displayed in blue.
A majority of IR inspection software and businesses require a means of documenting the outcomes of their activities. It is therefore crucial to use an infrared scanner which produces clear and precise reports. Numerous manufacturers offer free software that can be used for basic image analysis and report-making, while more advanced software is offered for deeper imaging and customization of reports.
Infrared sensor
The technology that makes up an infrared detector is used in a variety of security applications. This includes motion detection. If the sensor detects a change in the infrared radiation that is emitted by a particular object, it sends an electrical signal to a computer embedded that sets off an alarm. The sensor can also trigger other security systems like automatic doors and video recording. Infrared sensors can be used to identify the presence of a person and activate an opening mechanism for doors that does not require keys.
The majority of the time, infrared sensors can be utilized for motion-based detection. They utilize a pair of pyroelectric elements to detect infrared light and generate the electronic signal when the object is within their boundaries. They also allow for measuring the distance of an object from the sensor through measuring the amount of time required for the IR energy to bounce back.
While these sensors can be useful in securing structures, they are also susceptible to certain environmental variables. For example abrupt temperature fluctuations or excessive humidity can cause confusion to the sensor, resulting in false alarms. Dirt and dust can build up over time on the lens of the sensor, altering the ability of the sensor to detect infrared light.
It is crucial to consider the environment and location where an infrared detector is placed. It is also recommended to conduct professional inspections and maintenance of infrared sensors each and every now and. This will help ensure that the sensor is working properly and that an object is correctly detected.
