Abstract
Methods of performing electrostatic discharge testing on a transaction card are disclosed. A transaction card may be placed on an insulated surface. A grounding probe may be placed at a first location on the transaction card. A discharge probe may be charged to a known voltage level. The discharge probe may then be discharged at a second location on the transaction card. A discharge wave shape may be recorded from the ground probe, and one of a pass condition and a fail condition may be assigned based on at least the value of the known voltage level as compared to a reference voltage level. The first location and the second location may each be selected from a plurality of areas on the transaction card.
