Are portal keys sharable across factions in Ingress?

As the title says, are portal keys sharable across factions (through dropping) in Ingress?

In other words, if a member of the opposing faction drops a key on the ground, can I see it and pick it up?


Yes you can pick dropped items from the enemy faction.
