Abstract

The invention discloses a radio frequency laser compound card without through hole used in the mode of rotating read and write. There is a circular ring recording area of laser on the middle part of a side surface of plastic base plate. Being coated in sequence with sensitive layer, reflecting layer and protective film, the helical grooves are located within the recording area. IC module and rectangular radio receiving antenna are embedded in plastic protection layer that is agglutinated on the protective film. A piece having magnetic adhesion is embedded in the plastic protection layer at proper position. A printing layer is on the plastic protection layer. There is a blind hole in the center of base plate. A magnetic attracting piece is further inserted in the plastic protection layer at the position corresponding to the circular ring recording area of laser. The invention has advantages of integrality of the printing layer, raised collection, value, simplifying reading and writing mechanism, lowering cost and protecting wear of the card.

Description

technical field [0001] The invention relates to an information recording card, in particular to a rotary read-write radio-frequency laser composite card. Background technique [0002] At present, various information recording cards are constantly emerging on the market, including magnetic cards, contact IC cards, non-contact IC cards (radio frequency cards), laser cards, etc. Production and life have brought great convenience. Especially in recent years, various rotary read-write photoelectric composite cards and radio frequency laser composite cards have appeared. Since these composite cards integrate the IC card and the laser card on the same card, they have both strong IC card storage confidentiality and laser The advantage of the large storage capacity of the card is that one card can be used for several cards, which can basically save the user from the trouble of carrying multiple cards at the same time, which greatly facilitates the user. [0003] The structure of th...
