Implementing a custom error checker requires implementing a sub-class of op21_ErrorChecker, and overriding the _call_ method. The following error checker raises a SecurityRelatedException exception when sw1=0x66 and sw2=0x00.

Custom checkers can be used standalone, as in the following sample, or chained to other error checkers.
