Sensei is a Portugal-based cashier less checkout start and the leading EU provider of autonomous stores. To put it simply — scanning products and standing in lines are definitely things of the past. Sensei’s technology keeps track of the customer’s shopping baskets in real time, and once they are ready to check out, they can simply leave the store and will be charged automatically.To have such an ambitious mission is no easy task, and it required being able to communicate it simply.
