    Write a function to verify that a sequence of transaction IDs in the bank's fraud detection system contains no duplicate entries, ensuring each transaction being monitored is unique within the current analysis window. The function should examine a tuple of transaction reference numbers and determine if any transaction ID appears more than once, which could indicate potential fraudulent activity or system processing errors.
