Overview

Description

Currency counters are widely used products in most retail establishments. Typically, these counters feature a basic design consisting of little more than a motor-controlled counter. However, due to the prevalent issue of counterfeit currency, there is a significant market demand for currency counters that can accurately detect the legitimacy of banknotes. Such applications extend beyond the retail point of sales to include ATMs and other cash transactions, where speed, accuracy, and verification are essential. Our design addresses this market demand by offering a comprehensive system, incorporating the TMR sensor which ensures high accuracy through multiple scans.

System Benefits:

  • An MCU with high integration, USB for power supply, IrDA for support for multiple detection methods, and LCD for counter display
  • Accurate counterfeit detection
  • NFC for user authentication
