Rasool Allah peace be upon him said, "Whoever recites Aayatul Kursi after every Fard (Fard Salat). Only death is keeping him/her from entering Jannah. (As soon as he/she dies, will enter Jannah)
(Nisa'i, Ibne Habban, Ibnelsani A'n Abi Amatah Albahili Radiallah Anhu)
It's in another Hadis that Reciting Ayatul Kursi after one Fard (Fard Salat) will stay in Allah's protection until the next Salat.
(Tibrani Fil Kabeer, A'n Alhasan Bin Ali Radiallah Anhu)
Imam Bihaqi States that the one who recites Ayatul Kursi before falling asleep, Allah Tala gives protection to his/her home and his/her Family.
(Marqat Sharah Mishkaat, Mulla Ali Qaderi, vol. 2 pp. 583)
It's in another Hadis Jinns and Shaitans do not come close to the house in which Ayatul Kursi is recited. (Tirmizi Altargheeb Wal Tarheeb Lilmanzari vol.2 pp.631)
Hadrat A'isha Radiallah Anha states that a person arrived in the court of Nabi kareem Sallal Laaho Alaihi Wasallam and complained that there is no Barkat (Blessings) in anything in his home. Rasool Allah peace be upon him said, "You do not recite Ayatul Kursi, whichever Food and Curry you will recite Ayatul Kursi on, Allah Tala will give Blessings on that Food and Curry. (Tafseer Dar Manshoor vol. 1 pp. 323)
