Motorists get a receipt from the machine after entering the appropriate space number and paying.
The machines allow parking officials to see who has paid. Meter readers will issue warnings until May 1.
Business Administrator Michael Scott told The Press of Atlantic City officials hope the kiosks increase annual parking meter revenue from about $500,000 to about $750,000.
City officials raised the cost of parking last year from 25 cents to 50 cents per half-hour.
The machines accept cash, credit and debit cards.
The first kiosks were placed near Atlantic City Hall, the Atlantic County Civil Courthouse and near The Walk shopping district.
