The BitTag by Samuel Cox, a Creative Technologist at Belfast-, London- and New York-based rehabstudio, is a digital price tag that self-updates to show consumers the value of a merchandise in BitCoin. For those unfamiliar with BitCoin, it is "a peer-to-peer payment system and digital currency," as written on Wikipedia.
Slowly, BitCoin is being introduced in stores and the BitTag by Samuel Cox hopes to bridge the gap between traditional money and digital currency. Since the value of BitCoin fluctuates constantly quite like a stock, the BitTag connects to the Internet to display the right amount in real-time. It works with an accompanying iPad app. Cox states, "Being physical and therefore visible, [BitTag] will hopefully push Bitcoin to be accepted socially as a standard currency, decoupling it from its web roots."
