摘要：Methods, devices, and systems are provided for verifying tokens using limited-use certificates. For example, a user device can send a token request to a token providercomputer, and receive in response a token and a token certificate associated with thetoken. The token certificate may include, for example, a hash of the token and a digitalsignature by the token provider computer or another trusted entity. The user device canprovide the token and the token certificate to an access device. The access device canverify the token using the token certificate, and verify the token certificate using a digitalsignature. In some cases, the token and token certificate may be verified offline. Theaccess device can then conduct a transaction using the token.
