This bracelet-type transportation card was designed for the visually impaired. While in the subway, users can verify the station they are at or how many stations are left until their destination using the Braille on the bracelet. Also, vibrations from the bracelet will let riders know when to get off or when it is time to transfer so they do not have to worry about missing their stop.
