Hitachi RFID chips sleeps on the Singapore fishes



Keeping track of what fish is which can be difficult when there’s only a few of them, and when you’ve got a whole aquarium featuring hundreds of identical swimmers it can be close to an idiot savant talent. Underwaterworld Singapore has streamlined the process by using Hitachi RFID dust to tag individual fish with a lightweight payload that lets aquarium visitors easily tell an arapaima from a pacu. When the fish swims past a sensor, the name of the fish is displayed. The system cost a little under £10,000 to set in place and will be extended soon to include their shark population. [GT]
