The new "smart" bills were held back by multiple production delays before a printing error led the The U.S. Federal Reserve to incinerate 30 million bills, and begin the printing process again. Back in April, the Fed promised an Oct. 8 launch, and it seems they are on schedule.
The banknotes have new security features intended to make them more difficult to counterfeit. A three-dimensional security ribbon runs across the note and is printed with small bells. When the bill is tilted, the bells change to the figure "100."
Another security feature found by tilting the bill is that a color-shifting bell inside a copper-colored inkwell printed to the right of Franklin's face will turn green.
The bills retain many security features used previously, including raised printing, microprinting and security thread.
