Lidan protection science and Technology Co Ltd   

        bank card information is stored in the magnetic, magnetic stripe is composed of a magnetic medium composition, magnetic medium in ATM (ATM) machine under the action of electromagnetic waves emitted by the arranged your bank card information. But these magnetic media may be rearranged in the mobile phone or the electromagnetic oven and other equipment continuously emit electromagnetic waves under the action of card, resulting in loss of information -- high-tech materials which is the bank card degaussing
"Lidan" intelligent anti magnetic degaussing bag formed by the newly developed by special processing is made of. Bank card is put into the sleeve, external electromagnetic waves are attenuated by 10000 times or even 100000 times, low frequency electromagnetic field of bank card is not damaged will effectively protect the bank cards are not degaussing.
