The debate about using QR codes in voting: A move towards ensuring fair elections.

President Trump wants to change how votes are counted. He does not want machines to use ballots with barcodes. These codes are also called quick-response codes. This change could be big because many places use these machines. Some states use them for all voters.

Some people worry about these machines. They think the codes could be used to cheat. Trump says he wants to protect elections. Even some people who trust the machines want to change them. They say too many voters do not trust them.

Some places use pens and paper ballots. Others use touch screens that make paper records with codes. The codes are scanned to count the votes. Officials say the coded machines are safe and tested. But some people still worry about them.

Some people say worries about codes are too big. They think the codes are used to question past elections. They say this is not right. In Georgia, a scientist said codes could be changed to cheat. This has made people doubt the election results.

Trump's order about elections is being fought in court. Some lawsuits say Trump cannot tell the election commission what to do. The commission makes rules for voting. Some places are changing their voting machines. They want to remove the codes to make voters feel better.
