Abstract
Methods and systems related to distributing payment keys to multiple discrete devices in a point of sale (POS) system are disclosed. One method includes storing a payment key on a first discrete device for a POS system and a public key certificate on a second discrete device for the POS system. The method also includes communicatively connecting the first discrete device with the second discrete device using a wire, transmitting the public key certificate from the second discrete device to the first discrete device using the wire, and verifying the public key certificate on the first discrete device. The method also includes finalizing a secure connection between the first discrete device and the second discrete device over the wire using a transport layer secure (TLS) protocol after the public key certificate is verified.
