Accelerate checkout with your clients’ smartphones



KeySelf-Scan is a self-scanning software suite for iPhone, Android or Windows 8 smartphones and designed to replace self-scanning devices in store. Allow your customers to scan the article bar codes by themselves with their own phone's camera. They can then pay for the content of their shopping cart on a dedicated checkout. KeySelfScan significantly reduces shoppers queuing times at the checkout.


  • Equip your clients

    A smartphone app allows your customers to scan themselves the items they add to their shopping basket.

  • Reduce checkout time

    The clients transfer directly their shopping list to a checkout terminal to accelerate payment process.

  • No hardware costs

    Self-scanning devices are replaced by the client' smartphone, without additional charge for the store.

Step 1 :

After downloading your self-scanning app, the client logs-in when he arrives at your store. The application activates automatically, thanks to geolocation, which prevents its use out of your point of sale.

Step 2 :

During his shopping trip, the user scans barcodes items with the phones camera, and adds them to his shopping cart. He can also control in real time the amount of their basket as they shop.

Step 3 :

When completed its purchases, the user goes to a dedicated checkout and transfers the list of all items he has scanned.. This is done by scanning an end of transaction barcode placed on the checkout. He can then pay for purchases in a conventional manner (credit card, cash, etc.).

Step 4 :

Before leaving the store, the solution indicates to a store employee in charge of control if the basket should be re-scanned or not. If necessary, the operator can check the presence of some items in the basket to trigger validation. When done, the client can leave the store.




Our solution consists of 3 main modules that can be deployed independently:

KeySelf-Scan Mobile KeySelf-Scan Server KeySelf-Scan Control

KeySelfScan Mobile is a native iOS, Android or Windows 8 app installed on the customer's smartphone. It is through this application that users will be able to scan the bar code of their products and transfer the basket on the checkout to proceed with the payment.

An economical alternative to self-scanning devices in store

Self-scanning solutions with physical devices are now praised by users (between 10% and 20% of customers use it in store).

If you do not have any self-scanning server to connect your mobile apps, Keyneosoft proposes the setup of KeySelf-Scan Server, a modular middleware solution that manages the entire rules and content needed to run your mobile self-scanning solution:

  • Re-scan Management: the server solution may include a re-scan module to manage the tasks related to clients baskets control (see "KeySelf-Scan Control")

A multi-store management

KeySelf-Scan Server has been designed to work as well for a unique selling point than for a whole network of stores. From a single and centralized product catalogue, KeySelf-Scan Server can manage the specificities of each point of sale: prices, promotions, assortment, end of transactions barcodes, etc.

You can then deploy the solution quickly and progressively on all the stores of your network, while managing all product features centrally.


A solution connected to your systems

KeySelf-Scan Server is totally connected to your existing systems :

A complete self-scanning solution requires a basket control software powerful and customizable. This solution allows to determine, based on a set of criteria, whether the customer basket should or not be re-controlled by an operator of the store. The KeySelf-Scan Control module manages all rules and interfaces for testing customer’s basket. This module manages the 3 possible cases:

  • No control: You can leave the store with items directly after payment.
  • Partial control: the server determines random items that the operator must find and scan in the customer basket.
  • Total Control: The entire customer basket is re-scanned by the operator.

KeySelf-Scan Control consists of a server module for capturing re-scan rules as well as an interface for the re-scan operator device.


A complete and customizable re-scan engine (server)

KeySelf-Scan Control is a powerful and configurable re-scan module. It allows you to tune basket control rules that will determine the type of re-scan applied and which products should be checked. These rules allow tune the control criteria by :

  • Forced control / no-control
  • Customer Scoring: depends on the attendance of the store, the results of previous tests or the frequency of use.
  • Purchase day / day of the week: a specific weighting can be assigned to each day of the week.
  • Store: specific rules can be assigned to each point of sale.

A multi-devices interface
