The present disclosure relates to an optical fiber fan-out device having a furcation tube assembly. Each of the coverings has a plurality of holes defined therein for discharge of electricity therethrough, and is colored to match the main body whereby the personal safety device is disguised to prevent an attacker being forewarned of the punishment available from the device. Real-time detection is realized through piezoresistive transduction from the specially designed materials that form the nanowires. In one of the preferred embodiments of the invention the variable bar code system is compatible with the Universal Product Code currently in use in most retail shops.
