RFID Prescription Packaging for Dynamic Audible Label Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing prescription label technologies, such as RFID tags, have limited storage capacity and do not accommodate dynamic prescription information changes, and integrating them with mobile computing devices and pharmacy data systems presents challenges in data allocation, privacy compliance, and audible data presentation.
Innovation Solution
A system that includes a near-field memory device attached to a prescription container, a mobile computing device with a processor, memory, and a speaker, which reads and populates an audible script template using both local and remote prescription information sources to deliver prescription label information audibly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If RFID tags are used to store prescription label information, then wireless data communication capability is provided, but storage capacity is limited
Solution Approach 1:
The system divides prescription information into two segments: essential information stored locally on the RFID tag (such as patient identifier, prescription identifier, drug identifier) and comprehensive information stored remotely in the pharmacy data system. This segmentation allows the RFID tag to remain compact while providing access to complete prescription details through the mobile device's network connection.
Solution Approach 2:
The mobile computing device acts as an intermediary between the RFID tag and the pharmacy data system. It reads the identifier data from the RFID tag, retrieves comprehensive prescription information from the remote pharmacy data system using network communication, and presents the complete information to the user through audible output or display.
2Loss of information
If complete prescription label information is stored on RFID tags, then information completeness is improved, but manufacturing cost increases
Solution Approach 1:
The system extracts only the essential identifier information from the complete prescription label data and stores it on the RFID tag. The remaining comprehensive prescription information is extracted from the tag's storage requirements and relocated to the remote pharmacy data system, reducing RFID tag storage needs and manufacturing costs while maintaining information completeness through network access.
3Reliability
If multiple data sources are integrated for prescription information, then information accuracy and completeness are improved, but system complexity increases
Solution Approach 1:
The mobile computing device performs multiple functions: it reads RFID tags using near-field communication, stores prescription information locally, accesses the pharmacy data system via network communication, and provides audible output through text-to-speech conversion. This multi-functionality consolidates data integration complexity into a single device rather than requiring separate specialized components.
4Ease of operation
If audible delivery of prescription information is implemented, then accessibility for visually impaired users is improved, but device requirements and power consumption increase
Solution Approach 1:
The system uses partial action by providing audible output only when needed (when the user activates the text-to-speech function or when accessibility is required) rather than continuously. The mobile device leverages its existing speaker and text-to-speech capabilities that are already present for other functions, minimizing additional power consumption while improving accessibility.

AI summary
Pharmacy data systems, mobile computing devices, and methods for audible prescription label information using near-field encoded prescription packaging, such as prescription containers with radio frequency identifier (RFID) tags, are described. A mobile computing device, such as a smartphone, may include a near-field reader that reads a first set of prescription label information from an RFID attached to a prescription container. Using the first set of prescription label information, a second set of prescription label information may be accessed, such as from a remote pharmacy data system. The two sets of prescription label information may be used to populate an audible script template and converted to an audible human voice for delivery to the user.
