A new debit card-based digital currency service aims to get around one of the biggest problems faced by holders of bitcoin: the very limited number of outlets for spending or converting their digital currency.

Hong Kong-based startup Cryptex Card provides an online service for quickly converting bitcoins into dollars and loading them on a card that can then be used at ATMs and merchant-based point-of-sale card readers. The card, which will function like a prepaid debit card, will be issued under a license tied to Chinese card provider Union Pay, which is accepted in outlets all around the world including the Discover card network in the U.S.
