I signed up to the forum to answer this. I've had a Lucid for almost a year now and use Square, and as of June of 2012 the Square App -works-, but you cannot swipe a card with it, you have to enter the numbers manually. I contacted Square back then and they said eventually it will be supported, and since June 2012 there has been at least 2-3 Square updates since then.
So it's possible that swiping cards works now but I honestly haven't used Square since that time. Just know that the app will work even if the phone is not supported for swiping.
I just got 2 Samsung Galaxy Proclaim phones. We have a Square CC Reader. We have not used it as of yet. I will download th app for it to my phones. I have another question does anyone use the Kindle Fire for their Square CC Reader?
