Mobile POS Peripheral for EAS Tag Deactivation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current mobile Point Of Sale (POS) units lack a convenient method for deactivating Electronic Article Surveillance (EAS) tags, are not universally compatible with Near Field Communication (NFC) or Radio Frequency Identification (RFID) data transfer, and are fragile, making them unsuitable for rigorous retail operations and prone to theft.
Innovation Solution
A mobile POS device executes a software application to control a peripheral device for deactivating EAS tags via short-range communications like Bluetooth, allowing for NFC and RFID interactions, and is designed to be physically coupled with the POS device for enhanced mobility and security.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a mobile POS unit is used for purchase transactions, then mobility and operational flexibility are improved, but the device becomes fragile and vulnerable to theft
Solution Approach 1:
The system separates the mobile POS device from the EAS tag deactivation function by introducing a peripheral device. The mobile POS unit handles transactions while the peripheral device (attached to clothing or bag) handles tag deactivation, protecting the fragile POS unit from damage and theft while maintaining mobility.
Solution Approach 2:
A peripheral device acts as an intermediary between the mobile POS unit and the EAS tag. The peripheral receives commands from the mobile POS via Bluetooth and communicates with the EAS tag to deactivate it, allowing the fragile POS unit to remain protected while still enabling tag deactivation functionality.
2Reliability
If a fixed deactivation unit is used, then EAS tag deactivation is reliable, but customer convenience deteriorates due to post-POS tasks
Solution Approach 1:
The system transitions from a static fixed deactivation unit to a dynamic portable peripheral device that moves with the customer. The peripheral device can be attached to clothing or bags and provides real-time tag deactivation at the point of purchase, eliminating the need for customers to return to fixed deactivation points.
Solution Approach 2:
The peripheral device enables customers to deactivate EAS tags themselves immediately after purchase through the mobile POS system, without requiring assistance from staff or visits to fixed deactivation units. The device autonomously handles tag deactivation based on commands from the mobile POS.
3Adaptability or versatility
If NFC functionality is added to mobile POS units, then data transfer capability is improved, but device complexity and cost increase
Solution Approach 1:
The peripheral device serves multiple functions: it acts as a Bluetooth communication interface for the mobile POS, provides NFC/RFID capabilities for EAS tag interaction, and functions as a portable deactivation unit. This multi-functionality eliminates the need for the mobile POS unit to have built-in NFC hardware.
Solution Approach 2:
The peripheral device serves as an intermediary that provides NFC and RFID capabilities to the mobile POS system without requiring these features to be built into the POS unit itself. The peripheral handles all NFC/RFID communications with EAS tags while the mobile POS maintains its simpler configuration.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables convenient, secure, and mobile EAS tag deactivation, supports NFC and RFID data transfer, and enhances the ruggedness and security of mobile POS units, reducing theft and labor costs associated with lost hardware.
Implementation Method 1
a message is communicated from the mobile POS device to the peripheral device via a first short range communication (e.g., a Bluetooth communication)
Implementation Method 2
there is no general support for Near Field Communication ('NFC') or Radio Frequency Identification ('RFID') data transfer to and from mobile POS units
Implementation Method 3
The signal causes an actuation of a detachment mechanism of the security tag and/or a heating of an adhesive disposed on the security tag

AI summary
Systems (100) and methods (700) for operating a security tag of an Electronic Article Surveillance (“EAS”) system. The methods involve: executing on a mobile Point Of Sale (“POS”) device (104) an application operative to control operations of a peripheral device (190) attached to the mobile POS device for facilitating performance of a purchase transaction; receiving, by the mobile POS device a request to detach the security tag from an article; and communicating a message from the mobile POS device to the peripheral device via a first short range communication. The message is configured to cause the peripheral device to perform operations to facilitate a detachment of the security tag from the article. Next, a signal is communicated from the peripheral device to the security tag. The signal causes an actuation of a detachment mechanism of the security tag or a heating of an adhesive disposed on the security tag.
