! Suggestion

So I've one project based on fingerprint scanner where the scanner came with sdk for c# and other language libraries.
So basically the user punches for login and logout I'm storing timestamp based on that to MongoDB. Now the only concern is when the user punches, it doesn't give any response like sound or light for telling it's accepted or not.
For that I've to do something so my guess was
1. Sound
2. Light

But, it's for library and they don't want sound. And my scanner don't have any extra light for that.
Anyone got any suggestion or cool idea?
(I'm using Nitgen Fingkey Hamster I DX HFDU06)

    Maybe just do a hardware hack and add 2 LED's, then output a signal based on the result?

    @RhysOC yes, I'm thinking same but I need something cheap and something can be easily integrated, I don't know but is there any usb LED avilable?(I know it may sound dumb but i don't know much about it)

    @lazysnail same here but I'm sure there's a tut somewhere (I don't do that shit either).

    Good luck!

    @RhysOC Thank you. I found one called BlinkStick but its costly so never mind. Thinking about making my own small controller now haha
