Inditex, the Spanish fashion company that owns Zara, is installing iPads in the changing rooms of the popular fashion store, so customers can receive their last minute requests "as quickly as possible".
The idea - the first such scheme in the world of high-street fashion - allows customers to scan their items onto the iPad as soon as they enter the changing room.
They can then request different sizes or ask for an item of clothing to be brought to them that they have chosen at the last minute.
The iPad page will look similar to Zara's online store, and customers can choose garments in the same way they might if they were buying online, stipulating the size they want.
The item will then be brought to them by a member of staff.
Zara will test the scheme out in one of its biggest stores in Spain, then evaluate the results before deciding if it will roll out the idea across all of its stores worldwide, according to regional newspaper, La Voz de Galicia.
Several Inditex brands have been using the scheme, but so far it has been exclusively used by staff, allowing them to contact each other to request different items, or contact colleagues in different stores.
The changing room tablets are not the only idea that brings new technologies into Inditex's most popular stores.
The fashion behemoth is planning on installing a self-service till at the Zara store in Marineda, A Coruña in Galicia, where the brand was founded by Amancio Ortega, who recently overtook Bill Gates to become the richest man in the world.
Spain's fashion brands have been given a high-tech makeover in recent years. Popular high street stores Pull and Bear and Bershka have installed touch screens in their shops, allowing customers to check whether or not an item was out of stock.
