1. A retrievable token comprising:
- one or more physical channels of communication to at least one apparatus;
a first logical channel of communication to the at least one apparatus, wherein the first logical channel is associated with a physical channel of the one or more physical channels of communication, wherein the first logical channel is associated with a first protocol stack and a first execution environment on the retrievable token; and
a second logical channel of communication to the at least one apparatus, wherein the second logical channel is associated with the physical channel of the one or more physical channels of communication, wherein the second logical channel is associated with a second protocol stack and a second execution environment on the retrievable token,wherein the retrievable token is configured to concurrently execute the first execution environment and the second execution environment, andwherein executing the first execution environment comprises executing the first protocol stack and executing the second execution environment comprises executing the second protocol stack.
