Bitcoin Debit Card linked to the scam USD is NOT the solution to decentralized currency because it is still using the base currency known as the scam USD, ect...

People need to get stores to accept some form of cryptocurrency such as: Bitcoin, NXT, BitsharesX, Dogecoin, ect...
Consumers can pay using a plastic card that only link to cryptocurrency. The goal of this is to completely bypass the scam USD that's control by central banks.

Example:

A customer walks in to a store and pay using a plastic card that's only link to a certain cryptocurrency (Bitcoin, Dogecoin, NXT, BitsharesX, ect...)
The store takes that plastic card and swipe in the card reader and it deducts the amount in (Bitcoin, Dogecoin, NXT, BitsharesX, ect...).

This is the only way people be able to keep track of the total supply of the coins being distributed. The goal of completely bypassing the base currency USD is to allow the consumers to keep track of the total money being printed. This is the only way they can be reassure that their hard earned labor is not being taken advantage by some silly bankers.

New Challenge to Developers:
Developers must develop a magnetic strip card reader to function with their cryptocurrency.

Bitcoin debit cards stand alone version is a good idea.

But, Bitcoin debit cards linked to the base currency USD is a bad idea.

Because the bankers & their silly children can artificially inject unlimited supply of the scam USD into their "Bitcoin Debit Card" to purchase goods for free (not even for cheap, but for free) as long as the stupid humans continue to use their scam USD currency.

Example #2:
People go to store to buy an a mango using Bitcoin, that mango must have the same value for sale as the other mango for sale all over the world.
The price of a mango cannot be purchase for less or more in other country. I'm using mango as an example that represent all fruits, food, human labor, ect...
