Businesses, services and facilities announce their presence using ultra-high frequency (UHF) radio frequency identification (RFID) tags that operate at 915 MHz and can be read as far as 25 feet, or microwave frequency RFID tags that operate at 2.45 GHz and can be read as far away as 100 feet. Visually impaired people and others equipped with RFID readers with text-to-speech converters and speech synthesizers or Braille panels can then discover such businesses, services and facilities when they come within the range of these RFID tags. Furthermore, visually impaired and others can use the same RFID readers to read the RFID tags from items on store shelves, etc. to locate items of interest.
