https://blog.coinbase.com/2015/11/20/introducing-the-shift-card/Today, were excited to introduce the first US-issued bitcoin debit card, the Shift Card. The Shift Card is a VISA debit card that currently allows Coinbase users in twenty-four states in the U.S. to spend bitcoin online and offline at over 38 million merchants worldwide.
Wow. That really expands the number of stores you can spend Bitcoin at!
I hope they have fairer fees than the other Bitcoin credit cards.
Otherwise it won't affect the usage
And the coins will be easier to spend, so more sell pressure
