Wireless Security System for Cash Transfer Proximity Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The secure transfer of cash cassettes between secure vehicles and ATMs is vulnerable to theft due to time-activated security systems and the risk of unauthorized access, as security personnel must carry multiple identifiers and the transfer process is inconvenient, allowing potential thieves to access the ATP devices or ATMs.
Innovation Solution
A wireless security system using short-range and long-range communication devices to detect proximity between items and personnel, establishing a wireless link to prime and reset the security system, ensuring activation only during transport and deactivation upon arrival at the ATM, thereby eliminating the need for time-activated security and reducing the risk of unauthorized access.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a time-activated security system is used to protect cash cassettes during transport, then the security system can be activated automatically based on transit time, but the system may be incorrectly activated if security personnel are delayed and may not provide sufficient deterrence to thieves
Solution Approach 1:
The patent replaces the mechanical time-based activation system with a wireless communication-based system. The security system is activated not by elapsed time but by the establishment or loss of a wireless communication link between the ATP device and the secure vehicle, eliminating the problem of incorrect activation due to delays.
Solution Approach 2:
The security system automatically activates and deactivates based on the wireless communication link status without requiring manual intervention from security personnel. The system self-manages the activation state based on whether the ATP device is physically connected to the secure vehicle.
2Reliability
If security personnel carry identifiers to access ATP devices and ATMs, then they can authenticate and perform transfers, but this creates inconvenience and allows possibility of thieves obtaining codes/keys
Solution Approach 1:
The patent replaces the manual identifier-based authentication system with an automated wireless communication-based authentication system. The ATP device and secure vehicle automatically establish a wireless link to verify proximity and authorization, eliminating the need for security personnel to manually carry and input codes or keys.
Solution Approach 2:
The wireless communication system acts as an intermediary between the security personnel, ATP device, and secure vehicle. It automatically handles the authentication process by verifying the wireless link establishment, removing the burden of manual credential management from security personnel while maintaining security.
3Productivity
If cash cassettes are transferred manually from secure vehicle to ATM across the pavement, then the transfer can be completed, but the cassettes are most exposed to theft during this transport period
Solution Approach 1:
The security system is pre-configured to automatically activate before the ATP device leaves the secure vehicle and automatically deactivate upon arrival at the ATM. This preliminary setup ensures continuous security coverage during the entire vulnerable transport period without requiring manual activation/deactivation by security personnel.
Solution Approach 2:
The system continuously monitors the wireless communication link status between the ATP device and secure vehicle, providing real-time feedback on whether the ATP device is in a secure or vulnerable state. This feedback mechanism ensures the security system activation status always matches the actual physical state of the ATP device.

AI summary
A system and method for establishing and maintaining wireless communications links between a secure vehicle, a self-service terminal, and an item being transferred therebetween. The item to be transferred, the secure vehicle and the self-service terminal are equipped with short-range communications devices to enable the detection of proximity there between. The security personnel are also equipped with a short-range wireless communications device to enable the detection of proximity between the security personnel and the item. A security system of the item to be transferred is activated dependent upon the proximity between the security personnel and the item. The security system may be primed and turned off by detection of proximity between the short-range wireless communications devices of the item to be transferred and the secure vehicle or self-service terminal respectively.
