Is it possible to use one-click-buttons... like login with facebook or pay with paypal... on a landing Page? What methods these buttons use... are them based on simple text cookies? Is it possible to get useful data with that method? im thankfull for any hints and advises.

maybe u can have mine...depends on your offer. Its the nano tactical edition wich runs pretty well here in Rostock. (also u can have the yagi antenna and an alfa-card as 3rd antenna for the nano... and if needed a 32gb sd card)... Greetings Densen.
