Personalised checkout experiences that can be managed via computers, tablets and mobile phones are now an integral part of the retail experience. Check out systems that work with every card reader device or can be linked with existing online stores will be an important tool in future for any retailer looking to respond more rapidly and flexibly to their customers’ needs. A hush will fall over the traditional cash registers. At the hipster café around the corner or the latest neighbourhood pop-up store this has already been reality for some time now: instead of using old-school cash registers, payments are simply processed via a small wireless device. These mobile digital terminals also have the potential to appeal to more eco-minded generations thanks to functionality that makes it possible to send receipts directly to the customer’s smartphone via e-mail, SMS, WhatsApp, Facebook or other messaging services. All those annoying bits of paper are consigned to the dustbin of history, and users of the system can also ease their eco-conscience.
