Collectable cards have been part of childhood for generations, whether they came in packets of tea or cigarettes, wrapped in waxed paper with a strip of bubblegum or (more recently) purchased in their own right in shiny foil packs.
Another shift has been from collecting for its own sake to collecting in order to do better in a game involving the cards (think Pokemon).
A new twist combines children's love of collector cards with their love of touchscreen-based mobile devices.
According to local reseller Australian Geographic, the cards contain a circuit pattern which identifies the card to the app by channeling the hand's conductive energy in a distinctive way.
"A parent will love watching their six year old get lost in the Serengeti, whilst learning about endangered animals," said Claire Robertson, marketing and ecommerce manager for Australian Geographic Retail.
"Kids will enjoy the colourful cards, the entertaining game play, and trading their Nukotoys cards with their friends."
The same technology is used with Nuko's Monsterology app and cards for older children and adults.
Cards are sold by Australian Geographic in packs of seven for $6.96 and in "premium box sets" of 17 for $19.95.
