are detected to be operative to communicate with a card via any number of audible visible electrical or electromagnetic means as necessary while a card remains in activity mode 1102 of fig1 a card may re enter a detection search mode as in step 1106 for example to verify that a card either remains in a proximate or touching relationship with a device or to verify that a card has reentered into a proximate or touching relationship with a device similarly as discussed above delay 1108 may be optionally executed to reduce an amount of time that may be necessary to successfully execute the detection search of step 1106 persons skilled in the art will appreciate that the number of charge discharge sequences that may be executed during an active detection search may be reduced by delay 1108 without sacrificing the effectiveness of the detection search persons skilled in the art will further appreciate therefore that a reduction in the consumption of operational power may be realized fig1 shows flow charts of sequences 1210 1230 step 1211 of sequence 1210 may for example include placing a processor into a sleep mode whereby the processor draws little or no power during the sleep mode in step 1212 a processor may be awakened from a sleep mode to perform an activity during an activity mode the processor may for example be awakened from a sleep mode by an external event e g pressing of a button on a card in step 1213 a processor may for example.
