Yes, all wireless keyboards from Contour are secured by encryption.The communication between the dongle and the wireless product (2.4GHz) is secured by an algorithm called AES 128 bit, which is an industry standard when it comes to encryption on consumer devices.During the pairing process, a random encryption key is generated and exchanged between the dongle and the wireless device, and that is stored and used afterwards to secure the communication. The pairing process is kept secure by the fact that it happens only upon user request, and it is intentionally very short range which prevents eavesdropping.
