Bandai is using collectable cards to link the toys in its new Power Rangers Megaforce range.

All products in the line-up, which launches this summer, will come with at least one card from a collection of 180. They can be used with a smartphone app to unlock video footage, or to show the power of the card in a game.

The cards also interact with a Deluxe Gosei Morpher device. Cards can be inserted into the morpher - a replica of those used by the Power Rangers - to activate one of 180 different phrases of dialogue.

Other toys in the range include 10cm poseable action figures and the combining Gosei Great Megazord.
