The "Unique" feature of the "Fullbring" is the ability to change the form of an object to which they have a strong affinity. So Ginjo changed a cross-shaped medallion into a great sword. I am assuming that others change other things into different objects. So that's basically the "Zanpakuto"/"Resurrection" for this arc. The objects and what they can change into will differ from person to person.

Through Fullbring, Kubo seems to be plugging into the old Shinto concept of Tsukumogami which literally translates to Artifact Soul. From wikipedia "According to the Tsukumogami-emaki, tsukumogami originate from items or artifacts that have reached their 100th birthday and thus become alive and aware. Any object of this age, from swords to toys, can become a tsukumogami. Tsukumogami are considered spirits and supernatural beings, as opposed to enchanted items."

In a manner of speaking, Zanpakuto spirits themselves are Tsukumogami and I'll bet you that it'll soon be revealed that human with the Fullbring ability were either, Shinigami in their previous life or become Shinigami once they die, Maybe both and that's the Shinigami reincarnation cycle!

Still, Ginjo does have a substitute Shinigami badge, so it'll be interesting to find out what his connection with Soul Society is. I am still hopeful that Ginjo and his gang ends-up being the enemies for this arc because I am truly sick of everybody becoming Ichigo's nakame!
