Abstract
Technology is described for providing and using a thermo-sensitive payment card. An example payment card comprises a card substrate and a personalization layer overlaying the card substrate. The personalization layer includes a first region and a second region surrounding the first region. The first region includes an account number associated with an account of a user, and the account of the user is maintained by a payment service system that issues the payment card. At least one of the first region or the second region comprises a thermochromic ink such that application of heat to the first region or the second region having the thermochromic ink causes a change in color of the personalization layer so as to reveal the account number.
