An ATM mirror is a small, convex mirror commonly placed on top of Automated Teller Machines (ATMs) to enhance user security.
Purpose of an ATM Mirror
The primary function of the mirror on an ATM is to provide a simple yet effective security measure for the user. According to the reference, the mirror's placement allows the withdrawer to see if the person behind them is looking at his ATM pin or other essential facts. This helps users detect "shoulder surfing," a type of theft where someone observes a user entering their PIN or viewing account information.
Key Functions and Benefits
- Visual Security Check: Users can quickly scan the area behind them without turning around, maintaining focus on their transaction.
- Deters Crime: The presence of the mirror can discourage potential thieves from attempting to shoulder surf, as they know they might be seen.
- User Awareness: It promotes awareness among ATM users about the importance of checking their surroundings while conducting transactions.
Type of Mirror Used
Typically, a convex mirror is used. This type of mirror curves outward, providing a wider field of view than a flat mirror of the same size. This wide view is crucial for covering a larger area behind the user with a relatively small mirror.
Practical Insight
While ATM mirrors are a helpful security feature, they are just one part of safe ATM usage. Users should still take other precautions, such as covering the keypad when entering their PIN and being aware of anyone acting suspiciously nearby. The mirror serves as a valuable tool to aid in this situational awareness.
