The student Felix Mollinga, the Dutch James Dyson Award with an offline wallet for bitcoin.

The Acoin is a bitcoin that can be stored in a special cabinet, which is wirelessly linked to a corresponding smartphone app. The saved amount on a display.

Money can be transferred to other devices by a ngerprint scanner to press. By two Acoin-drives next to each other to keep and the second swipe, the money can also go to the other drive to be transferred. A third option is to have an Acoin with a certain amount physically to someone else.

According to Mollinga may not be maintained where the bitcoins will be used, since they are on the drive offline to be preserved. The money is only to trace as it is being transferred to an online account, but then it is not to see which path the bitcoins have passed.

“Not to fake it

Although the money offline is met, according to Mollinga still safe. “Acoin used for the storage of currency called cryptovaluta ‘keys'”, says the creator opposite “That entire long unique codes, which is the value of wear of a X number of cryptovaluta. Cryptovaluta are designed so that your codes can’t fake it.”

“If you have a Acoin opening, and other (‘false’) data on the memory, then the data the next time that a user is back on his bank account to convert is denied. Because it is no ‘real’ money.”


The student wants with his invention payment transactions more anonymous. “Our spending reflect who we are and what we do,” says Mollinga. “With a cashless future disappears also our freedom for anonymous transactions, and Acoin is a solution for this problem.”

Mollinga has the national award, of which an amount of $ 2,500 is awarded. He is looking now to the international award, which over a month is awarded with a prize amount of $ 40,000.
