In the unfortunate case that your Chime Card is lost or stolen, you can disable transactions in the Settings section of your Chime app or at www.chime.com. Under Card Settings, toggle the Allow transactions switch to the grey position. In the security section of the Settings page, turn off Chime Card Transactions. This will immediately prevent any more transactions on your card.
If you need a new Chime Card, tap the "Replace My Card" button in the Card Settings of your Chime app! You will be asked whether your card was Lost, Stolen, or Damaged. After confirming your address a replacement card will arrive within two weeks. Keep an eye out for a green envelop with a Salt Lake City, Utah return address!
