Scheme je besplatna aplikacija razvijena od strane istoimene firme sa ciljem da omogući otvaranje ormarića na različitim lokacijama u zemlji. Na mnogim lokacijama se mogu videti ormarići za odlaganje stvari ili paketomati i tome slično. Trenutno aplikacija radi samo za ormariće kreirane od strane Scheme tima, kao na primer u Naučno tehnološkom parku u Nišu, gde postoje set ormara u kojima se nalaze knjige i drugi edukativni materijal.
