Reader Object

Create

The operations of the MercuryAPI are centered around a single object that represents the
state of the reader. This object is called “Reader”. Except when otherwise specified, all

The user obtains a

Reader object by calling a static factory method:

Reader create(String uriString);

create() method return an instance of a Reader class that is associated with a

RFID reader on the communication channel specified by the

URI Syntax

uriString parameter. There are currently two subclasses of Reader:
