SINGAPORE STARTUP'S PHYSICAL BITCOIN BANKNOTES

Physical bitcoins have been around for some time and are now collectibles. Physical bitcoin banknotes are less common. Time will tell if any of them catch on. Before anyone notices, let me note upfront that this news is a few years old - it just popped up for some reason in a Google alert. The company still exists and their website is active, with a new blog article posted just this week. -Editor

Tangem bitcoin banknotes A Singaporean startup developing ‘smart banknotes' for cryptocurrencies has launched sales of physical bitcoin banknotes with a pilot in a major Singaporean mall.

Describing itself as a ‘smart banknote platform' that manufactures physical notes with denominated values of cryptocurrencies like bitcoin, Singaporean firm Tangem has debuted ‘Tangem Note(s)' in a pilot launch at the Suntech City shopping center in the city-state today.

The ‘banknotes' will carry their value in bitcoin on a chip inside each note and are available in denominations of 0.01 BTC ($98) and 0.05 BTC ($485) at launch. The hardware inside each banknote – it isn't made of paper – is a Samsung Semiconductor S3D350A chip which, according to Tangem co-founder Andrew Pantyukhin says, ‘addresses all known attack vectors on hardware and software levels on a Medium post. The accompanying cold wallet is uncopiable, Tangem says, while its co-founder insists the hacking of a single banknote would prove ‘uneconomical' and would only be restricted to a single banknote even in the event of a hack.

Each banknote costs the company $2 to manufacture. The co-founder says the company is ‘making millions of units now' in a bid to facilitate crypto transactions that are immediate, free and anonymous.

Pertinently, transferring ownership of the notes and their value in bitcoin is instant when the banknote swaps hands. Physically hand over the whole wallet together with the blockchain private key. No transaction fees, no need to await confirmation blockchain, Tangem states on its website, adding that each note will be NFC-enabled, allowing a user to instantly verify the validity of the assets contained via a smartphone.

These look more like chip cards than banknotes. Has anyone encountered them? -Editor
