Fingerprint lock

Hi all!

I would like to develop a fingerprint lock with Arduino.
The plan is to use it later with a Website, where the users would book timeslots and in that manner would be given access to the room.

But the first things first...

I can not decide between following readers:

Could you recommend me one?

Definitely go with the first link. ( Have you clicked on it? )

Grumpy_Mike:

I corrected the link.

Now, regarding the fingerprint readers.
What is the difference between the two. Why should I use the first one?

I only said the first one because it linked to a stupid page, I had no idea where it linked to.
They look prity much the same to me, I can't see any great advantage between the two from the spec sheet. Try and find out if any one has used both.

At least the adafruit one has an Arduino library. Not clear if the SparkFun one does.
