what is hurigana?

I was trying to contact this one japanese company to ask a question...and for some reason it asked for something called Hurigana and then said "sei" and "may". I am a bit confused since I have never heard of hurigana or how this is used for contacting companies...can someone explained?

Brio,

The "hurigana" you are hearing is "furigana", the reading (pronunciation) of Japanese kanji words or names using kana.
See: http://en.wikipedia.org/wiki/Furigana

"Sei" means family name.
"Mei" means given name.

Since I have an american name is it possible to find a way around this seeing how furigana applies to kanji?

Furigana can be used for Romaji as well- if a company wants my name and then asks for furigana, I write my name in Romaji and then use katakana for the furigana- quite standard.
