Linkyfi is a simple marketing tool that uses the mechanism of conditional access to the Internet to collect data about its users. To surf the Internet the client logs on to the Linkyfi platform- by entering the phone number or e-mail address, logging via social media accounts or by completing a short questionnaire. An in-depth analysis of the customer information allows the business owner to create and send customized advertising campaigns directly to the clients. Additionally, the client may be offered the possibility of using virtual menu, virtual points/stamps or navigation to selected places.
