서울 버스 교통카드 단말기, 승하차 구분해 음성안내 한다

Buses in Seoul will get a slight upgrade to keep you from accidentally paying your fare twice.
Starting next month, card readers will let you know you paid with a verbal message instead of just a single beep and will also have guidance in English.
If the card isn't tagged properly, the reader will show a red X and ask you to try again.
The city says some customers have paid twice when they didn't realize that their card had worked and so tagged it again.
