In the US there is no standard way of voting. Elections are run by each of the 54 states and territories. Each one of those have varying standards. Within most states the state itself provides certain rules that must be followed but the election is actually overseen by the local government and there may substancial leeway regarding how the locality implements the rules. Within each locality different polling places may use different technologies. I have even been to polling places where there were differing ways to vote within the same location. In general polling places are run by volunteers and each candidate is allowed to have representatives at the polling place.
