Transparent/translucent financial transaction card |
摘要 |
A financial transaction card is transparent or translucent to human viewing yet detectable by automated card processing equipment. The card includes a substantially planar material sheet having upper and lower surfaces bounded by a continuous peripheral edge. The material sheet has one or more areas that are at least minimally transparent or translucent to human viewing. A filter associated with at least one of the areas provides sufficient opacity to light used by card sensors in the automated card processing equipment to render the card detectable.
