摘要： 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 sendee 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.
