The present method has advantages over conventional approaches. The first advantage provides for an individual WL or BL is able to be detected as not being connected or defective in terms of leakage using the present method. In contrast, the conventional approaches involve shorting the all BL's together and all WL's together to make a single measurement, which has at least two disadvantages. The first disadvantage includes the possibility of determining whether a card was “present” with only a couple good connections, instead of all 5. The second disadvantage includes using a voltage of 1.8V versus the present method that uses a measurement using ?12V, which allows a higher noise tolerance in the measurements that increases reliability. The second advantage avoids the need for the additional writes and reads to determine if the connection is good, which may not fatigue the material of the printed memory device as much as a full read as the state of the material is not changing. The present method may only change a small portion of the polarization if any. However, after thousands of card detection executions, the state of the cells is still in or close to the original state. This helps in extending the life of the printed memory device as there is already a limited amount by which the printed memory device can be written or read.
