how to match finger print detail with out loop?
Short answer: you don't.
If you store simple bitmaps of finger prints, the only way to match an unknown finger print is to check against everyone in database. There is a loop, explicit or implicit (hidden).

So, it's Slow when Data is huge.
Indeed, that is the principle.
The only speedup I can think of is to do some analyze of prints to extract key points and their relative positions and use this information as a kind of index.
