Unofficial results of the draft charter referendum from 95% of all voting stations will be known in three hours after the vote ends, according to election commissioners.
"This is half the 6-7 hours it normally took in the past. The official results with documents will be ready three days later, said EC commissioner Somchai Srisuthiyakorn.
The EC unveiled the sample of the voting ticket on Monday.
The ballot, of A5 (half A4) size, is the same size used in the 2007 charter referendum and has two parts in different colours.
The top part is the main question where people can choose from one of the two choices to endorse the draft constitution or not. There will be no "No Vote" box. The lower part is the extra question, with two choices as well.
However, the colours shown in the sample are not final as the EC keeps some details confidential.
The ballot will have medium security, with a tiny code that can be seen only with a 30-time magnifier, Mr Somchai said.
Votes will be counted separately for each part. If different marks are made in one of both parts or no marks are made, the ticket will be considered invalid. A voter can choose to vote one or both questions.
The EC will print 53 million ballots, costing one baht each, plus an additional 8% to cope with contingencies.
EC chairman Supachai Somcharoen said the EC had asked for a 2.99-billion-baht budget for the referendum at around 100,000 voting stations.
"After constitution writers send us the final draft by Wednesday, we'll meet on Monday to fix the date and decide how different groups can discuss the charter or campaign under the new referendum law. Guidelines will also be made for people so they know what can or cannot be done during the lead-up to the referendum, tentatively set on Aug 7.
The EC also agreed to back down on its proposal that the National Legislation Assembly (NLA) simplify the language in the second referendum question, saying it was up to the NLA which insisted it was too late to change.
The extra question to be asked is: "In order to ensure continuity in the implementation of national reform under the national strategy during the five-year transition period, do you agree that a joint sitting of parliament should be allowed to vote to select a prime minister and that this should be included in a provisional clause [of the draft charter]?"
