Introduction
CRK is an innovative solution designed to automate and improve the cash chip redemption process in casinos. By integrating various hardware components such as RFID and NFC readers, receipt printers, and cash dispensers, CRK enhances efficiency and accuracy at cage counters, reducing the need for manual intervention. This system addressing the unique challenges faced by their accounting department and cashier operations on the casino floor.
Problem
The manual processes involved in casino chip-to-cash redemptions are time-consuming and prone to errors, leading to inefficiencies and potential discrepancies in financial records. Operating in a high-volume, 24/7 casino environment demanded a secure, automated solution capable of identifying chips, validating transactions and coordinating multiple hardware devices reliably, without constant manual intervention.
Solution
CRK's core application functionality was built using C#, .NET Framework 4.5 and WPF, handling chip identification, denomination processing, transaction management, device control and user interaction. The workflow reads and identifies casino chips, determines their denominations and value, validates the transaction, and initiates the corresponding cash payout — with hardware integration and communication logic coordinating multiple devices within a single transaction. External systems were integrated through APIs and BizTalk to support transaction processing and back-office communication, and the application was designed for continuous 24/7 operation with error handling and device-status monitoring in a high-volume casino environment.
