The incipient technological possibilities have generated a new commercial model where the seller becomes a purchase advisor, offering a personalized service that includes accepting payments at the moment, combining the online and physical experience, and offering a payment experience that will benefit both businesses as well as consumers.Scan and pay At the level of mobile-based payment options, there is Scan & Pay that allows the customer to scan a QR code related to the product using an application.Payment is made through the merchant's application, which eliminates the need for a cashier service and, in turn, queues, giving back power and autonomy to customers, as they are the ones who decide the time it takes for a merchant to shop and the time of payment.Traditional mobile payment system (MPOS) Another way to gain mobility are the so-called MPOS (Mobile POS) systems that are used to process transactions, but work through a mobile point of sale integrated with the merchant's application.Vendors can be equipped with a device (MPOS) that acts as a POS, through which the customer makes the payment from their mobile or card.In this way, the same seller is the one who executes the collection from any point of the store.But in practice they have been more complex to use, since an extra device must be added to the solution and in some cases printers must be included.Mobility in payments without Hardware This is when the great demand of businesses arises to reduce their investment in CAPEX.Its complexity in development means that few payment companies have implemented it, but since 2021, Worldline has provided its clients with a Software-based mobility solution available for Android devices and that is already being implemented in different clients in Europe.The common element of all these forms of payment is mobility in the store.As there are no checkout areas, crowds and queues are avoided, allowing customers to pay at any point in the store, either with a sales advisor, through a mobile application or a portable terminal.“Mobility in the store is the key to personalizing the purchase process, evolving the role of the sales consultant giving them total freedom in the store and thus being able to offer a 100% personalized service to the customer, impacting and including in the decision of purchase”, says Miguel Álvarez, who is responsible for sales at Worldline Iberia."In this way, the payment process goes beyond a simple transaction and becomes an opportunity to forge a deeper relationship with the customer, improving and promoting cross-selling."In conclusion, consumers continue to demand faster and more convenient ways to pay in stores.Many retail businesses are already adapting to meet these requests, providing the services customers need to be able to pay as they go, without the need to wait in line.Therefore, inevitably, the queue days are numbered and businesses that do not adapt to customer demands, reducing payment barriers, run the risk of losing sales.
