Abstract
Methods, systems, and products for radio frequency identification aiding the visually impaired, storing a recording of a sound representing at least one attribute of an object having associated with the object a radio frequency identification (“RFID”) tag; activating the RFID tag with an electronic travel aid (“ETA”) for the visually impaired; retrieving the recording from storage; and playing the recording through an audio interface of the ETA. Storage of sound recording may be local or remote, and sound recordings may be sorted or indexed and retrieved from storage according to an RFID tag identification code, a classification code for the object, and a type code (a sound skin identifier) for the recording.
