Abstract

The invention discloses a destroying and reclamation technique of waste chip cards and intelligent cards which is used for treating and destroying various waste chip cards and intelligent cards and recycling the metal and non-metal materials in the cards; the technique includes the following technique steps: (1) the cards are cracked into pieces of a certain size; (2) an eddy current sorting is carried out on the pieces to sort the pieces into metal pieces and non-metal pieces; (3) the metal pieces are grinded into powders by an eddy current mill; (4) a high voltage static separation is carried out on the powder to sort the powder into metal powders and non-metal powders; (5) the dust which is generated in the processes of grinding and high voltage static separation is collected by a pulse bag dust catcher. The technique of the invention realizes the complete information destroying of the chip cards and the intelligent cards as well as resource recycling and solves the difficulty that the current chip cards and the intelligent cards can not be treated in batch; the treatment process is safe and environment protective without secondary pollution and has the broad practicability.

Description

technical field [0001] The invention relates to the fields of information security and resource reuse; in particular, it relates to a processing technology for waste chip cards and smart cards. Background technique [0002] With the continuous development of information technology, the application of various chip cards and smart cards has brought great convenience to people and has been widely used in various fields. As time goes by, there will be a large number of chip cards and smart cards that are scrapped and expired. On the one hand, the processing of such cards involves the confidential destruction of the data in the cards. On the other hand, these cards can recover the usable part through resource regeneration, so professional processing of such cards is urgently needed. [0003] The treatment process of waste chip cards and smart cards can refer to the treatment methods of electronic waste according to the characteristics of their material composition. At present, ...
