What Does a Coin Acceptor Supplier Do?

A coin acceptor supplier will provide a device to verify the authenticity of coins. This is done by evaluating the coins on various parameters like size, weight, alloy constitution & more.

These devices decode coin values through logic signal pulses which is then read by the host controller. They are available in different types based on the currency and work well in varied environments from gaming to amusement, kiosk and car wash.

Authenticity Detectors

Authenticity detectors are a common feature of coin acceptors and are designed to validate coins as being the correct currency. They do this by using various sensors to evaluate a coin’s weight, size, magnetism and optics as well as testing the coins alloy composition. If a coin does not match the expected characteristics it is rejected by the coin acceptor and the operator is informed.

The preferred embodiment of this invention relates to a rapid coin acceptor comprising a coin introduction chute, a coin sensing gate receiving coins by gravity from the coin introduction chute and means associated with the coin sensing gate to check the authenticity of a coin or token directly within the coin sensing gate. Sensors 40, 42 disposed within the coin sensing gate are designed to receive signal inputs indicative of a genuine coin and, upon receipt thereof, operate to rapidly move the coin sensing gate from a normal, first vertically coin reject position 24 to a second, coin accept position 26.

The coin discriminator 3 includes a capacitive-type thickness detector, and the sensor coils (42, 46) disposed adjacent to a coin path 44 are connected in a circuit to a current ramp generator 48 operable under control of a system control coin acceptor supplier means 50. The sensor electrodes (4, 5) positioned in the coin path are each provided with one capacitor plate, and the sensor coils are configured to monitor changes in circuit performance characteristics effected by the presence of a coin in the field of the sensor coil, from which a characteristic representative of the coin detected, yet essentially independent of circuit component parameters can be derived.

Magnetic Detectors

Some older acceptors use a low frequency magnetic detection method which compares the change in the frequency and amplitude of an oscillating magnetic field as the coin passes between two coils. This is based on the principle that different coins have different magnetic characteristics – each one reduces the magnetic field intensity by an amount which is different from the other types of coin.

The coin is first inserted into the coin slot which then pushes it past an inductor coil containing a soft iron band. A permanent magnet arranged close to the coils serves to magnetise this band, first in one direction when the coin enters the coil and then in the other as it leaves the coil. This reversal of the magnetisation causes a voltage to be generated in the secondary coil and this is used to detect if the coin is accepted.

A comparator is connected to the output of the Schmitt device, the input to which is provided with the electric signal originated by mechanical vibration produced by the impact or knocking of the coin on the metal piece. If said electric signal is higher than the reference threshold set in the comparator, it activates the switch (8) for applying power to the electronic coin control and measuring system.

Miniature magnetic sensor technology is in high demand for advanced intelligent measurement and control systems. While other emerging sensor technologies, such as giant magneto resistance (GMR) and fluxgate sensors, have proven their value in a variety of applications, the magnetic field sensing technology developed by Analog Devices, called Magneto Impedance, offers unique advantages including high sensitivity and rapid response.

Optical Detectors

Optical detectors are a type of sensor that measures the power of a beam of light passing through a device. They can be used for a variety Game console supplier of purposes, including determining whether a coin is valid. They are typically made from photo-conductive semiconductors. These include silicon and germanium photo-diodes. The photo-conductors are operated under reverse bias, which enables the electron holes produced by photons incident on the p-n junction to combine with each other to form minority carriers. The power received by the detector is proportional to the number of these carriers.

In some embodiments, an optical detection system includes a digital image acquisition device that can acquire a digital image of a coin when the coin enters the viewfield of the camera. The digital image can be in either color or gray scale.

The digital image can be analyzed using various algorithms to determine the characteristics of the coin, such as the coin diameter and other features. For example, the outer edge of a coin can be detected by measuring the intensity or location of one or more peaks in a spectral plot of the digital image using marching schemes such as Canny edge detection.

A coin acceptor can be a complex piece of machinery, and it needs to be able to work with a wide range of coins. In addition to detecting and recognizing the different types of coins, it must also be able to deal with the many environmental conditions that can impact the performance of the machine, such as dust, dirt, and oil. A good coin acceptor will be able to withstand these conditions without compromising the integrity of the machine.

Security & Fraud Detectors

Fraud detection systems act as an early warning system by monitoring transactions and user behavior for patterns that could indicate fraudulent activity. They use machine learning to process massive amounts of data and identify hidden correlations between users’ behavior and their financial transactions to spot anomalies. These systems can be a valuable tool for banks, credit card companies, ecommerce platforms, B2B fintech, and other businesses that deal with large numbers of financial transactions.

Coin fraud is often a problem for businesses that accept coins and paper money as payment. To protect their machines from counterfeiters, some vendors use security features that can recognize foreign or altered coins. The sensors in these devices can detect alterations to the coin’s appearance, texture, or weight, and reject the counterfeit coins from a machine’s acceptance hopper.

These sensor technologies are constantly updated to keep up with new counterfeiting schemes, so it’s important to work with a supplier that is committed to staying on top of the latest developments. For example, Crane Payment Innovations works closely with the U.S. Department of Treasury to ensure that its validator firmware is up-to-date. Tidel is able to ‘push’ the updated firmware out to its entire installed base of smart safes, so that any changes are automatically reflected in the machine’s software.

The best way to reduce the risk of financial fraud is through comprehensive, real-time prevention measures. These include using a combination of advanced technology, including smart coin acceptance solutions that are capable of identifying fake currency and other suspicious anomalies. By detecting and stopping fraudulent activities before they occur, businesses can limit their losses and protect customer trust and loyalty.
