Tandem String
Two goals of using barcodes with blockchain technology; 1: Eliminate counterfeit identifications through a unique key verification system. 2: Use tracking and traceability aspects of the blockchain to track and monitor products throughout their life-cycle.
Project Description
Under the same roof of technological features, Tandem Strings attacks two distinct fields: Identity verification and logistical product challenges. Tandem String integrates blockchain technology encrypted into PDF417 barcodes to enhance license security by restricting access to authorized users and assigning unique codes to cardholders, ensuring data protection and preventing unauthorized alterations. The blockchain's role in verifying keys ensures an extra layer of security, making unauthorized access or forgery nearly impossible through the precise alignment of both the cardholder's key and its documentation on the blockchain. Tandem String is also addressing the challenge of accurately tracing and documenting products in the current supply chain industry. Tandem String’s logistical blockchain solution leverages blockchain technology with the common corporate (UPC) barcode, offering a cost-effective approach to improve product management. Additionally, Tandem String’s blockchain solution uses reliable geolocation tracking, enabling companies to navigate logistical complexities with confidence. Targeted recalls are facilitated by an immutable ledger, ensuring accountability and trust throughout the supply chain. Tandem String aims to fight fraud and counterfeiting, improve recall procedures, and minimize product loss.
How it's Made
Serverless = Vercel: Serverless functions on Vercel can generate and validate barcodes, embedding identity information that is associated with unique identifiers stored securely on a blockchain through smart contracts. Its ability to run code on-demand without needing to manage infrastructure, provision servers, or upgrade hardware is a crucial step for logistical real time tracking and product management. As devices scan barcodes, serverless application programming interfaces (APIs) on Vercel handle geolocation tracking, collecting and updating data on the blockchain. Vercel's auto-scaling capability effectively handles different traffic volumes, and blockchain's decentralized and cryptographic characteristics guarantee safe, transparent, and unchangeable identity and logistical data storage. Vercel's serverless architecture, blockchain technology, and barcodes come together to provide a scalable, affordable, and safe solution for geolocation tracking and identity verification. Tandem String is built on the polygon chain using Layer 2 (L2) to enhance transaction flow rate and reduce fees. Tandem String is able to have faster and more cost-effective transaction processes through Polygon's architecture. L2 highlights a constant increase in scalability through a decentralized application (DApp). This L2 blockchain technology enhances the overall efficiency and user experience of DApps on the Ethereum ecosystem. Tandem String operates with 100% on chain code. This allows secure data and trust from users. With the use of L2 technology, Tandem String is able to use attainable fees to monitor all transactions. With the ability to scale at a quick rate Tandem String has the capacity to create side chains for all Admins. Each sidechain will have complete autonomy over all data in and out of their respective chains.
