This deck is based on the website:
http://pianochorddictionary.com/
For each chord there are four cards.
1:- Two recognizion cards, one for the left hand , the other for the right.(This may be useful when you come across a chord in a score )
2.- Two production cards , one for the left hand , the other for the right.
in which you will have the chord name and you have to make a mental representation of the chord (This is useful when you play jazz or have some indications of the chords in a score)
Besides you will have some indications for each chord :
RH= Right hand
LH= Left hand
inv1= First inversion
inv2= Second inversion
inv3= Third inversion
1 = thumb
2 = index finger
3 = middle finger
4 = ring finger
5 = little finger
The deck also contains some suggestions for the fingerings, However everybody has their own needs , so you can edit the field and choose a fingering that works for you.
I will suggest to study the theory of chords First. Then you could start working through this desk and use the formulas you have learned to review the flashcards.
The notation I used is the simpler I found in

Disclaimer: I have been using this deck personally for a couple of months. I did it manually so maybe there are a couple of mistakes in it (I did not notice one) I would like to hear some feedback or suggestions for improvement.
