No chips. Fake chips. The computer chip issues are still with us.

Let’s talk about computer chips. We’ve told you that they’re in short supply — because of COVID and materials shortages and shipping problems, and because a lot more people have bought digital devices during the pandemic. Sometimes when there is low supply and high demand, lots of counterfeits appear on the market. These could be chips taken out of old electronics and resold as new. Some of the fake chips work, to a certain extent, and some don’t work at all. Marketplace’s Marielle Segarra speaks with Bill Cardoso, CEO of Creative Electron, a company that uses X-rays to inspect chips and see if they’re real.
