The French firm Thales is launching a credit card that talks. Not to embarrass users for their spending habits, but to make transactions more secure for people with a visual impairments. About 250 million people worldwide have some form of visual impairment, according to the World Health Organization, and in France they’re often targeted in fraud schemes because of their disability. The new Thales credit card connects users with a phone app that verbalizes transactions. In Paris, John Laurenson tagged along as one person tried it out.
