RFID Makes an Aquarium Visit More Memorable

If you’ve ever travelled to a zoo or an aquarium with a child, you’ve probably been asked dozens of times, "What’s that? What is it?"

In Singapore, moms and dads can impress their offspring with accurate information about each fish that swims by at the Underwater World Singapore. That’s because some fish there are tagged with RFID. Each time a tagged fish swims by an antenna mounted outside the tank, information about the fish pops up on a screen. Parents can then teach their children about a fish’s diet or its habitat, and it allows visitors to identify fast-moving fish that may look similar to one another.

Seven species in the so-called Living Fossils tank, including the Arapaima, Alligator Gar and Redtail Catfish, carry the tags.
