The phone turned into a card reader
Mortadelo uses his shoe as a phone, the shoe-phone. The Navarre engineering firm Muxunav manages to turn the mobile phone into a card reader so that services can be charged directly.
Plumbers, home painters, small shopkeepers, taxi drivers, home cleaners, home carpenters, babysitters or wedding planners are some of the more than 47,000 self-employed workers registered in Navarre who will be able to turn their phone into a virtual card reader to charge their customers.
It will be possible thanks to the electronic payment method developed by the Navarre engineering firm Muxunav. That is why the company has reached an agreement with ATA, the Spanish Association of Self-Employed Workers, to offer its members special conditions.
This payment method works through a website called LaKuenta, where the person providing the service must register. Depending on the plan chosen, the user will pay €7 a month or €76 a year.
LaKuenta can be accessed from a mobile, tablet or PDA. Upon entering, the user enters the amount for the product or service they want to charge for and the system generates a QR code that the end customer must scan with their phone’s camera.
The website incorporates as payment methods bank card, Bizum, Google Pay and Apple Pay. Once the payment is confirmed, the system generates an invoice for download.
Muxunav is an engineering firm specialising in the development of hardware and software for digital payment systems. Driven by engineer Antonio Torres, it has eight employees and expects to turn over €2 million this year.
In addition, the company has patented Telmarkt, a system that makes it possible to enable contactless payments on old vending machines.
