The invention provides for marking unique and customized information onto product labels, eliminating the need for pre-printed labels. The means of marking breaks the marking into two parts, constant data and product unique data. This allows programmable marking of product on demand. Constant data is shown in Fig. 1 and can be either a silk screen mark, transfer mark or label. The mark or label is then placed on a frame or product so it can be seen from the outside of the product. The label is then marked with product unique data via a laser by discoloring or burning the label with the appropriate data. In an application of marking serial numbers (S/Ns) on a label, such as on a card cover assembly, the data needed has been stored in memory on the card. The flow is as shown in Fig. 2.
