Using SD cards on Raspberry Pi, we have developed our Blockmesh Networking technology ByteBlock that allows for online to offline to offline then back online data editing transfers without duplication or loss.
This is one of our result screens, we are able to edit and trade crypto data offline as part of an online connected public ledger.
Here is an example of multiple transactions coming through from both of the Raspberry Pi's
Quickfuse will pair with your smartphone or smart device and allow the ability to transfer with other offline devices updated by ByteBlock securely.
Fusepro allows the network to work both online and offline. It's the device that allows for supply chain tracking at scale as well as merchant payment processing.
Shortfuse Wallet will serve in the place of the QuickFuse paired with a smart device in the event the use case requires it or the user does not have a smart device nor wishes to use one. This hardware wallet fixes that.
