Abstract: Device for storing and protecting data for domestic animals includes housing configured for and sufficiently strong for being worn by an animal in an outside environment. There may be an attachment device, such as a collar, configured for attaching housing to an external portion of the animal, in use. There may likewise be provided an electronic data storage device within the housing. The electronic data storage device may include software written for storing animal medical and ownership identification data, veterinarian, and medical records, and which records relate to the animal wearing the device. The housing may be sufficiently water-proof for being continually worn outdoors by the animal. The identification device may include a type-A USB connection so that the information stored on the data storage device may be easily accessed and read by a large portion of the population, without the a specialized data reading device.
