Hermes has spent £18m on handheld technology to improve its customers’ experience.

The 20,000 devices, which will all be in operation by the summer with couriers and in myHermes parcel shops, have improved GPS tracking technology.

The carrier said they would allow it to reduce the delivery windows it gives to customers to two hours by the end of 2016.

The 4G enabled devices have a 10 hour battery life, and will allow parcels be tracked all the way to customers’ doorstep.

Hermes chief executive Carole Woodhead said: “Our aim is to achieve 100% first time delivery success as well as industry-leading customer choice and convenience. We continually place innovation at the heart of our business and this substantial investment equips us with the capability to add premium features such as ETA to a standard product.

“This strengthens Hermes’ positioning in the UK delivery industry as the market leader in innovating and changing the face of standard delivery at standard prices.”
