摘要:
The invention concerns an embossing plate for a hot-cold-laminating press with a three-dimensional structure based on an essentially flawless metal plate with a hardened surface of appropriate thickness and dimensions and a suitable surface, specifically a highly polished surface, into which or onto which the three-dimensional structure is incorporated by a process with at least two steps.An embossing plate produced by this process is used for the production of documents, specifically security documents, such as personal identity cards, passports, identification cards, credit cards, customer cards, driving licenses and similar sheet and/or card and/or book-like documents by means of hot-cold-lamination and/or embossing and/or item-by-item embossing.
摘要:
A method for memory management in smart card controllers by writing of data into a data space in a persistent memory is described. In order to save memory space the persistent memory is split into blocks with fixed data length having logical block numbers; whereby the size of blocks is selected such that it corresponds to the physical size of the pages of the EEPROM memory existing on the card. Fragmented blocks are used by comprising segments being independent from each other, whereby these segments are part of different data fields. A Block Allocation Table (BAT) is used in order to distinguish the physical place of the block in memory from the logical block number and to address different segments in the block.
