Abstract
A transaction card comprises an optical card created using CD-ROM technology which can be read and erased but not reprogrammed. The optical transaction card is programmed (i.e., written to) at bit increments representing, in total, the stated value of the card; and, is then decremented by erasing the incremental bits during use. Once bits have been erased, they cannot be reprogrammed.
