The Kansas Lottery is seeking permission from legislators to sell tickets from vending machines.
A hearing on the bill scheduled for Wednesday before the House Commerce, Labor and Economic Development Committee was postponed indefinitely while the bill is refined.
Lottery officials believe eliminating the state's ban on electronic ticket-dispensing machines would boost sales and provide additional revenues for the state.
The bill also would repeal a ban on lottery advertising at college sporting events, though ads still would be barred at high school events.
The Kansas Constitution once banned all lotteries, but voters approved an amendment in 1986 to allow one operated by the state. That provision later allowed legislators to authorize a single state-owned casino in each of four communities.
