How does the card work?

The power source to make the cards work is by means of body heat, energy or light. The card can release far infrared rays that would resonate with the energy emitted from the human body that can improve local blood circulation, strengthen the immune function and general well being.
 

How fast does the card work?

Its effectiveness can be felt from about 20 minutes to 30 days. It all depends on the card and each individual’s health condition.
 

Why is far infrared ray good for the health of human body?

In fact all material can emit energy waves under room temperature. In physics this is called the "blackbody radiation". But the energy waves have different wavelengths and different effects to the human body. For example, when the wavelength of an ultraviolet ray is 320 nanometers, it may burn the skin. When the wavelength is 400 nanometers, it may cause the skin to yield sunspots. But those wave bands beneficial to the health of human body only happen to lie within a few narrow ranges that are synchronous with the wave emitted from human body. It is called the "rejuvenating light", "biological wave", "energy of universe" etc. A very weak external far infrared ray resonating with the wave emitted from human body may achieve the unique effect of regulating the physiology of human body.

Are the cards safe?
The cards have passed the cytotoxin test conducted by PSB Corporation of Singapore. Moreover, it is meant for external application and not meant for consumption.

How effective are the cards?
It ranges from 80% to 99% depending on the category of card.

Can the cards be shared and used by family members?
Yes indeed, except for the Fridge fresh card.
