Event based interrogation zone tracking system for product samples
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Festivals and fairs face challenges in collecting and compiling consumer behavior data in real time due to their temporary nature, leading to inefficient marketing and sales processes for vendors, and consumers face inconvenience with cash-based transactions.
Innovation Solution
A system utilizing RFID tags embedded in wristbands for tracking consumer interactions and enabling cashless payments, which collects data in real time and facilitates electronic transactions, allowing for post-event engagement and data analysis.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If RFID tags and readers are deployed throughout the festival grounds, then consumer behavior data collection capability is improved, but system complexity and implementation cost increase
Solution Approach 1:
The system divides the festival venue into multiple interrogation zones, each with its own RFID reader. This segmentation allows data collection to be distributed across multiple simple units rather than requiring one complex centralized system, reducing overall implementation complexity while maintaining comprehensive data collection coverage.
Solution Approach 2:
The RFID wristbands serve multiple functions: they act as identification credentials for festival entry, track consumer movement and behavior across zones, and enable cashless transactions at vendor booths. This multi-functionality consolidates what would otherwise require separate systems into a single unified solution, reducing overall system complexity.
2Productivity
If manual cash transactions are used at vendor booths, then transaction simplicity is maintained, but transaction time and vendor workload increase
Solution Approach 1:
The system replaces manual cash handling with automated RFID-based electronic transactions. The RFID reader automatically deducts funds from the consumer's wristband account and notifies the vendor's mobile device, eliminating the mechanical processes of physical cash counting, verification, and change provision that currently slow down transactions.
3Loss of time
If RFID readers are placed at every vendor booth, then real-time transaction tracking is improved, but device deployment cost and complexity increase
Solution Approach 1:
The system replaces static RFID readers at fixed vendor booths with dynamic mobile devices that vendors can carry. This allows transaction tracking to move with the vendor rather than requiring fixed infrastructure at every location, significantly reducing the number of permanent devices needed while maintaining real-time tracking capability.
Solution Approach 2:
The vendor's mobile device automatically receives real-time notifications of transactions through the network system without requiring dedicated RFID reader hardware at the vendor's location. The system serves itself by using existing mobile communication infrastructure rather than requiring specialized tracking devices at each point of sale.
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
This system enhances data collection and marketing efficiency for vendors, reduces transaction time and cash handling for consumers, and encourages spending by providing a convenient and efficient payment method, extending commercial interactions beyond the event.
Implementation Method 1
RFID tags allow for a 'tap and go' style of payment because the information is transmitted wirelessly. Two-way radio transmitter-receivers called 'readers' send a signal to the tag and read its response.
Implementation Method 2
Other types of RFID tags may use a local power source such as a battery, or else have no battery but collect energy from the interrogating electromagnetic field, and then act as a passive transponder to emit microwaves or UHF (ultra high frequency) radio waves.
Data Source
AI summary
The invention provides a temporary installation of a system of RFID-based terminals and user-worn RFID devices within an event interrogation zone. At an event, terminals are located within, and associated with, vendor booths erected in the interrogation zone. User RFID devices are issued to users wishing to enter the interrogation zone. Each user RFID device includes an element worn by the user, and an attached or embedded RFID tag with a stored unique UserID. Products for sampling have unique ProductIDs. The terminals are programmed for: (1) retrieving the UserID when the user enters the vendor booth; (2) retrieving a ProductID of a product sampled by the user; and (3) retrieving the UserID when the user leaves the vendor booth. The UserID and timestamps of entry, departure, and ProductIDs of products sampled are communicated to a server. The system allows tracking of products sampled and user behavior during an event.
