NO-STACKS
I can read. HI this is my propose, i started working on the concept u give us. I prefer to focus in that thing you say, representing the layers integrated in one logo. One layer (top of one) its activated, the others are like inactive. Also work on the letters , i have fuse the o with the line for mor clarity and simple form. Less characters, more explained and you always can use only the words for some cases . I think i really like the slogan, but i changed a little, it's says a lot of from the producto, and u can use it or not depends the case without change the logo. For the personal card i will work later this but im thinking in a 2 sides one, with the logo and the slogan in the first and adding some contact facts backside, putting a QRL code to get access directly with a cellphone (to the web or the app for downoad). Hope you like it, still in contact for more details.
