Dualscan LLC, a leading innovator in the digital transaction space, is thrilled to announce the launch of the 7ollar℠ app, a licensed application of CardPay℠ International's variPIN℠ technology. The 7ollar app is designed to enhance the security and efficiency of peer-to-peer (P2P) transactions, addressing the growing need for secure and interoperable digital transaction platforms.
In addition to the launch of the 7ollar app, Dualscan LLC is excited to announce the availability of CardPay International's variPIN AWS API for developers and personal integrations. This API allows developers to integrate the innovative variPIN technology into their own applications, further enhancing the security and efficiency of digital transactions. Commercial plans for the variPIN AWS API are also available, providing businesses with a robust solution for their digital transaction needs.
The 7ollar app leverages the innovative variPIN technology from CardPay International, a global FinTech services firm renowned for its cutting-edge solutions. This technology allows for the tokenization of ETH addresses, creating a unique Digital ID for each user. This Digital ID is used for transaction authentication, significantly reducing the risk of fraudulent transactions.
The 7ollar app also integrates with Wallet Connect to capture the consumer ETH wallet address. This allows for real-time transaction authentication, further enhancing the security of transactions. The use of variPIN clock passcodes, delivered from CardPay International's AWS variPIN Clock API leasing services, adds an additional layer of security.
"We are excited to bring the 7ollar app to the market," said Liz Charles, Innovation Director for Dualscan LLC. "We believe that this app, with its unique approach to transaction security and interoperability, will revolutionize the digital transaction space.”
