Effect: 
You can immediately tell the audience how many cards they cut, which card is cut to, and even what the next card will be. You can also let three spectators randomly cut the deck and memorize the randomly cut cards, and you know what cards they are immediately. You can even perform with 7 different types of memorized deck stacks, like Mnemonica. Furthermore, you can also put aside the playing cards and use objects from daily life, such as keys, coins, cigarettes, chewing gum, dice, etc. 
Possibilities: 
The high-tech chip has seven built-in 7 types of stacks: including new card order, Mnemonica, Si Stebbins, etc., whether you are a beginner or a professional, you can use it very easily. You can use any playing card with different weights since you can calibrate the weight of each card. 
Our high-precision sensor & dual-mode master chip: the accuracy is as high as 0.01 grams, enabling SOUL to accurately read any small objects on the device. It doesn't even have to be used in a card box; it can be installed anywhere that is suitable for the size, like a book, mat, table, etc. Soul has a built-in memory function; after Calibration the data can be automatically saved even when the machine is turned off. Say goodbye to the frequent resetting.
