From Bitcoin to banknotes. The cryptocurrency is becoming tangible: 10,000 notes have been manufactured and sent to Singapore this month, a product of the Swiss startup Tangem. A confirmation that the digital is not always practical? The Bitcoin media is now a cryptocurrency converted into a ticket that moves to a new dimension: the real world. It may seem an oxymoron, but the digital currency is now available in two denominations, the 0.01 and 0.05 BTC, which can be found in Singapore's Suntec City Megafash store. Manufactured by the Swiss start-up Tangem, the ticket contains an integrated hardware system based on one of Samsung's semiconductor chips. The tickets are "cheap enough to exchange them" and, according to Bitcoin News, "they do not need special infrastructure or complicated applications". The user simply needs a smartphone with NFC capability to verify the assets of the ticket. Zug's company claims that these smart notes are "comparable to the well protected paper ticket", a clear recognition that tangible money is indeed a safe and practical tool for a variety of transactions. The important thing is that the circle is closing: from digital to tangible and from cryptocurrency to banknote. Even on Tangem's website, the company talks about a product "similar to cash" to promote its digital ticket. The message is loud and clear, as is the motivation behind Tangem's offer, that cryptocurrencies are generally not accessible to the majority of the population, since they are not well understood and are not particularly easy to use. The advantage of a ticket is that it is concrete and that a transaction requires nothing more than a simple exchange of bills. No computers, no sophisticated infrastructure, no WiFi. Tangem sent the first 10,000 copies to Singapore earlier this month, after having undergone an extensive security audit by the Kudelski Group.
