So, the test needs to be 3-dimensional instead of the 2-dimensional test now used. Flattened-then-trimmed cards meet the 2-dimensional test, but with diminished thickness. They will have to measure the thickness of the card, particularly at the edges. This may require new/additional equipment, but should be technologically feasible and, just as important to PSA's business model, economical.
