Data Cables and connectors are an expensive and environmentally critical part of M2M (Machine to Machine) communication. Using the Kronegger NFC Data Link modules, this cable can be avoided by using a contactless near field communication based on NFC standards. Implementing a contactless DataLink is straightforward using Kronegger NFC modem modules. Communication is specially limited to a few centimeters, allowing for stable connections without interference from neighboring channels. The modules are CE and FCC certified.
