Product Description: The Intelligent Comparitor® with Valence Sensor is designed to further protect against counterfeiting. The Valence Sensor device senses the surface characteristics of a coin. This sensor provides enhanced security when used in conjuction with dollar casino tokens minted in either 752 nickel silver or 6% high security alloy composition. Product Details: Microcontroller technology High security algorithm for microcontroller Simplified coil balancing procedure Improved sensor coil design provides a better coin signature for the microcontroller High speed throughput of coins and valid coin acceptance I/O is optically isolated from the microcontroller Valence Sensor incorporated for even higher discrimination of lead slugs On-board voltages are maintained by fixed boltage regulators of lead slugs Inhibit feature offered on all models IC-16, IC-32/33, IC-36/37, IC-40 and IC-62 are directly retrofittable in most applications Product Description: The Intelligent Comparitor® with SmartMark® reader is designed to further protect against counterfeiting by incorporating a bar code optic unit. The bar code optic device is designed to work in conjunction with SmartMark® tokens which are manufactured by the Roger Williams Mint (www.mintusa.com). This device reads precision mirrors that are accurately minted into the SmartMark® token when the token is manufactured. The SmartMark® is minted into the coin with great precision. The relationship between the center of the mass of the coin and the placement of the bar code is fixed into a specific pattern producing the entire coin signature. This combination of variables makes counterfeiting extremely difficult.
