This invention includes an electrolysis chamber and method for producing controlled flow acid electrolyzed water and controlled flow alkaline electrolyzed water with independent flows from aqueous solutions. A viscosity of the ink can be adjusted by adding high boiling point solvents. Then, a first set of stimuli patterns is presented on a display and a first set of signals from the electrodes is received. The theoretical impedance values are compared to the measured impedance values to allow a modification direction to be determined for at least one of the parameter value estimates. The wake-up module is configured to provide an indication to wake-up the reader from the sleep mode responsive to detecting a change in power of the electromagnetic field caused by the credential device. Other text data is recorded together with language code.
