IC~ カード (IC Card). Mine is an ICOCA イコカ, which I purchased in Osaka! Now here's the thing, I LOVE these e-cards! I also have one from my stay in South Korea! You can use these in many places: train, bus (I think), taxi, konbini or convenience stores, vending machines, etc. We were even able to use this when we went to Tokyo so we didn't need to buy another PASMO or SUICA card. ✨
P.S. Had to trace the word cause it was too difficult! Hahahaha! 😔
