The Sirin Finney joins a selection of new phones dedicated to accessing the blockchain while you're away from your PC. And it does so in safety with a nifty little hardware trick.

Named after the late Hal Finney, the first person to receive a bitcoin transaction, the Finney is a crypto-focused device from Israeli company Sirin. Sirin launched with the outrageously decadent $16,000 Solarin phone in 2016, but the Finney will cost $1,000 (which converts to roughly £750 or AU$1,780).
