Blockchain technology has been slow to take off in the restaurant industry. But the launch of a new credit card currently accepted by Palo Alto, Calif. merchants and restaurants could help restaurants see the tangible benefits. Restaurant Dive reports that Yosemite X, a technology company that developed a public blockchain platform, has just launched Yosemite Card, a 0 percent transaction fee credit card that is expected to save businesses 2-3 percent on transaction costs annually. It generates a random PIN every 30 seconds, which could provide protection against data breaches, and it can also integrate with a restaurant’s existing systems to offer a rewards program. The technology could still be a ways off from being widespread in the industry, but applications like this could well provide telling data points about how blockchain can help restaurants improve margins, as well as manage and protect their data.
