The Insight system includes a miniature wrist-worn reader and a deck of 52 electronic playing cards. 

The smallest RFID reader available, Insight can detect playing cards at up to 11cm (4.5 in) away. A simple vibration cue will tell you the suit and value of the card within seconds. 

The basic effect 

The performer hands the deck to a volunteer and invites them to choose their favourite card, placing the rest of the deck aside. Without touching the volunteer or the deck, the performer reveals the chosen card. 

An almost infinite variety of effects can be performed - you're limited only by your imagination! 

The reader 

The reader features wireless transmission and on-board vibration cuing. At only 77 x 33mm it's incredibly small, with a range that allows you to detect cards and tags with a single gesture. The battery will last for over 10 hours on a single charge and is both rechargeable and replaceable. 

The deck 

The Insight deck (Phoenix edition) is the very first electronic deck to be designed from the ground up specifically for magicians. The chips and antenna are incorporated into the cards during the manufacturing process, ensuring that each card is perfectly thin and flat. The deck can be shuffled and handled in the same way as an ordinary deck. 

Single and double sided blank cards are available from the store, as well as ultra-thin adhesive tags that can be used to make your own props. 

And finally... 

iPhone users can unlock the wireless features of their device by purchasing the Insight app available from the App Store. This allows for wireless cuing, reprogramming and more.
