All digital currency via an implanted chip? That is scary, how will I buy my weed?! More than that, they really have not thought this through as it appears to have no system for consumer to consumer selling such as yard sales, buying a used car from a regular person, family helping out their friends and family if they are broke or giving your kids an allowance, money getting lost by people wrecking and falling in the water, burning to death, getting murdered and buried or burned, like what happens if they wanted to pay half for a car and pay the other half later but then die before they can? Also paying a maid or a baby sitter which in many cases is not through a company
Sure they could make the technology where you can give money to each other by putting the chips close together but how would you control how much it transfers? If you set it up that way your spouse could accidentally rob you while having sex or sleeping, if the chips get too close, robbery could still happen if they restrain you. And giving money to a personal person, it's not going to show why it will only show the transfer. So they still would not know everything we do.
Really this plan has so many problems I doubt we need to worry about it, there is a whole economic world amongst the consumers who have a right to provide services independently or sale their stuff on their own and I'm sure there are many other flaws. It would be funny if everyone went modern medieval and suddenly withdrew all the paper cash out of the banks and littered the banks and the streets with deactivated cards.
