Prism Changer

The Prism Changer (プリズムチェンジャー Purizumu Chenjā) is a transformation device which the Prism Hearts Precure use to transform into Precure, using Prism Cards. The Cures swipe their Prism Cards to transform into their corresponding Cure forms and Prism Changes into the previous Cures.

Appearance
The Prism Changer is an arm brace that resembles a mixture of a wrist device and a smartwatch. It has three jewel-like buttons at the bottom, all of them being pink, blue, and yellow, the main color scheme of most Precure trios. The top plate of the Prism Changer is different depending on the Mascot who has transformed into it, but in Cure Echo's case it lacks the top plate. There is a scanner the left or right side that a Prism Card can be swiped across in order to activate the transformation, which causes the screen to display the Pretty Cure Insignia alongside their respective colors
