Claim Text:
1. An apparatus comprising: a signal conductor capable of radiating signals in one or more distinct bands having a side that is configured to be disposed proximal to a surface of part of a first biological entity to use as a transmission channel to transmit a signal received by the signal conductor from a first electrical device, the signal transmitted as a guided wave substantially undetectable outside of the first biological entity; and a ground layer arranged coaxially next to the signal conductor and configured to be disposed on an opposing side of the signal conductor from the side of the signal conductor that is configured to be disposed against the surface of the part of the first biological entity, the coaxial configuration of the ground layer in relation to the signal conductor causing formation of a coaxial channel using the part of the first biological entity to serve as the transmission channel, wherein part of the first biological entity and part of a second biological entity in contact with one another communicate purchase credentials over the transmission channel between the first device and a second device of another apparatus as a result of the contact between the parts of the first and second biological entities, and wherein the other apparatus comprises another signal conductor and the signal conductors of the first and second devices are disposed proximal to surfaces of the parts of the first and second biological entities.
