Abstract: A mechanism is provided for automatically making payments using a cryptocurrency address embedded in a passive radio-frequency identification (RFID) device. Responsive to receiving an indication, from a first user, of a payment to be made to a second user, cryptocurrency information is retrieved from a second user device associated with the second user. Responsive to receiving the cryptocurrency information, a payment transaction is generated with a cryptocurrency service provider via a network. A status response is received from the cryptocurrency service provider indicating a status of a transfer of an indicated amount of cryptocurrency from a cryptocurrency address of the first user to a cryptocurrency address of the second user completing. Based on the status response, an indication is provided to the first user that the payment transaction has completed.
