About

Launched in 2014, Nucleus Vision, also known as nCash, aims to bridge the divide between the online and offline retail world. The project is an IoT-based, contactless identification system that enables retailers to identify and better serve their customers by using customer’s records to make precise decisions on product preferences without the use of WiFi or Bluetooth.
