2. Aldi UK

Discount retailers are tech laggards, right? Aldi UK is trialling new checkout free technology in one of its London stores.

The discount retailer says that the tech will allow customers to scan a smartphone app to enter the store, pick up their shopping, and walk out without the need to pay at a till.

They will then receive an email receipt and be charged automatically using their chosen payment method.

A press release did not mention where in London the trial is taking place, or which tech firm Aldi is working with on the project.

It did reveal, however, that staff are currently involved in the test, and further testing will be carried out with the public.

3. Nisa

Jisp has launched an augmented reality vouchering system, Scan & Save, for brands, independent retailers and their customers. 

The solution will initially be deployed in 12 Nisa stores across the UK and will allow customers to exclusively save up to 60% on more than 65 products from the likes of Mondelez, PepsiCo, Kelloggs, Molson Coors and Nomad Foods.
