Ronaldsway Airport will spend £40,000 on boarding card readers - and £70,000 on building work to improve security waiting times.
The figures have been given in response to a freedom of information request to the Department of Infrastructure.
The DOI was asked to breakdown the £300,000 figure given by minister Ray Harmer when he announced plans to cut long queues.
The airport will also spend £80,000 each on two automatic tray return machines, and £30,000 on equipment to monitor queues.
