E-cash Application

Since 2020, Carrousel Digital has been committed to digital security by providing solutions to security flaws that are still overlooked. Carrousel Digital has therefore developed various processes to improve cybersecurity: these processes have been patented, testifying their novelty.

 

What is the Moneytak cash application?

 

Carrousel have developed the Moneytak POC application which enables cash transfer by simply placing two phones running the app back‑to‑back. This allows users to spend or share their cash in any situation, even when the network is down or permanently offline, by passing it to another person with the same app, or by using it over the internet.

 

Once the network is online, the Moneytak app can be used like any other payment app, or to credit the money it holds to the user’s bank account.

 

This app could also be used to pay with credits, for example, health credits that have been provided to pay for a medical service and it can also be enhanced to carry the associated service report.

This application benefits from the Random Hash technology, as well transaction chaining. It uses the NFC capability of phones to transfer money once the amount has been entered and the two devices are placed back‑to‑back.

Can you please describe the other technics?

 

They each address a different problem and implement different technologies, sometimes very innovative, sometimes more traditional:
•  The security of encryption keys is addressed by a patent relating to an electronic circuit that 'automatically' erases a memory space (containing encryption keys) when the data in another memory space (containing the code of a software) is modified, rendering hardware whose firmware would have been fraudulently uncovered unusable.
•  An innovative  mechanism for transmitting information using entangled photons makes it possible to communicate in post-quantum security, by optical fibers or by satellite.
•  A geolocation system that uses electromagnetic waves in the UHF to longwave range makes it possible to locate the counterparty of an online transaction, or a user, even when they are indoors and without any satellite use.
