Abstract
Commerce card techniques are described. In one or more implementations, one or more credentials are received at a commerce card, the credentials encrypted using a public key. The one or more credentials are decrypted using a private key that corresponds to the public key, the decrypting performed by a secure element implemented in tamper-resistant hardware of the commerce card without exposing the private key outside of the secure element. The decrypted one or more credentials are stored within the secure element of the commerce card such that the decrypted one or more credentials are not exposed outside of the secure element, the one or more credentials usable by the commerce card as part of a transaction to purchase a good or service.
