Niches are eyelashes for the front of your car....that's a niche. MYDOSE, SAFEDOSE, EMS, MMS, FIELDLOCK to name a few are not niche...not even close. The technology is not niche as IPhone, Android have proven...this list goes on. Nothing niche about Fingerprint Technology.
Everything I say is in my opinion, do your own DD and make your decision wisely! Don't spend more then you can afford to lose!
