A method, a system, and computer readable medium comprising instructions for real-time monitoring of agent adherence. The system incorporates a controller configured to select a radio operating mode. After the data transfer, the portable data storage module reenters the sleep mode. The variable capacitor can include first and second actuation electrodes wherein one of the actuation electrodes is movable with respect to the other actuation electrode when a voltage is applied across the first and second actuation electrodes. In response to an operator signal, the source data value and data type of a source data item in the array is obtained and indirectly represented in the Data Pane image.
