Embedded on-board diagnostic (OBD) device for a vehicle

An on-board diagnostic (OBD) device for a vehicle, comprising:

• at least one memory configured to store OBD data of the vehicle received from an OBD port of the vehicle;
• a radio frequency identification (RFID) tag electrically coupled to the at least one memory and configured to communicate at least a portion of the received OBD data to a first RFID reader when queried by the first RFID reader;
• and
• a wireless communication module comprising an antenna, the wireless communication module electrically coupled to the at least one memory and configured to communicate the at least a portion of the received OBD data to a second reader based in part on the RFID tag communicating the at least a portion of the received OBD data to the first RFID reader,
• wherein the OBD device is configured to operate in a pass-through mode and a continuous mode, wherein, in pass-through mode, the OBD data of the vehicle is retrieved via the OBD port and communicated to the first RFID reader automatically in response to the query from the first RFID reader and, in continuous mode, OBD data of the vehicle is stored in the at least one memory for subsequent communication to the first RFID reader when the first RFID tag is queried by the first RFID reader.

A method for providing on-board diagnostic (OBD) data of a vehicle to a plurality of RFID readers, comprising:

• querying, from an OBD port of the vehicle, OBD data of the vehicle using an OBD device coupled with the OBD port;
• storing the received OBD data into a memory of the OBD device;
• and
• receiving a first query from a first RFID reader for at least a portion of the stored OBD data of the vehicle;
• transmitting the at least a first portion of the stored OBD data to the first RFID reader using a first RFID tag of the OBD device;
• and
• transmitting the at least a portion of the stored OBD data to a second RFID reader using a second RFID tag of the OBD device based in part on the first RFID tag transmitting the at least a portion of the stored OBD data to the first RFID reader,
• wherein at least one of the first RFID tag and the second RFID tag is configured as a passive RFID tag which functions without requiring power from either a vehicle or the OBD device.

An on-board diagnostic (OBD) system, the system comprising:

• an OBD device coupled to a vehicle, the OBD device comprising:
• at least one memory configured to store OBD data of the vehicle received from an OBD port of the vehicle,
• a first radio frequency identification (RFID) tag electrically coupled to the at least one memory and configured to communicate at least a portion of the received OBD data to a first RFID reader when queried by the first RFID reader, and
• a second RFID tag electrically coupled to the at least one memory and configured to communicate the at least a portion of the received OBD data to a second RFID reader based in part on the first RFID tag communicating the at least a portion of the received OBD data to the first RFID reader, wherein at least one of the first RFID tag and the second RFID tag is configured as a passive RFID tag which functions without requiring power from either a vehicle or the OBD device;
• a computing device communicatively coupled to the first RFID reader, the first RFID reader configured to (i) query the first RFID tag for the at least a portion of the OBD data when the vehicle passes the by the first RFID reader, and (ii) forward the at least a portion of the OBD data to the computing device, the computing device configured to generate and transmit checkout information based on the received at least a portion of the OBD data;
• and
• a user device comprising the second RFID reader, the user device communicatively coupled to the computing device via a network and configured to receive the checkout information from the computing device, the second RFID reader configured to query the second RFID tag based on the received checkout information, and the user device configured to verify the received checkout information based on the at least a portion of the OBD data received from the second RFID tag.
