Damn it! Again wanted Good!:) And so I think what you need to activate SMS to send and if not send an SMS that is not activated.
And if we assume that all the same key has already been activated but the user has not been sent SMS about the activation key and sold to another, who also sent an SMS that goes out that does not track! Because people, for example the distributor (network marketing) and have activated everything such as 10 keys and sell them! This in theory is possible! And can not keep track! Remains in the context of the key word for the seller, and the people are known, are dishonest! Protection is very weak, based on the consciousness.
Interestingly, the level of connectedness increases(the meaning is clear, but the mechanism of this of course is not!) With the structure of Chamber Benefits what happens with the structure of the key? Should something happen, once one card becomes stronger and the other gives the power and gives it only once. But in the parlor, no magnetic components and some material variables. Physically then nothing can not be changed!
In General, I thought! If the keys are so easily activated and their numbers are participating indirectly in the process of activation(i.e., activation is possible without a number), then any key can be activated unscrupulous seller or even someone who has access to them, even if to make a protective layer of the key number! What is the theme of keys as it is not thought out!
And, you can assume that Keys and room Good lay next to and part or all of the keys are activated, even without the participation of the seller...
