EMScardQ&A

QI think magnetic materials are prone to oxidation, but is this a problem with durability?

AThe magnetic material is sandwiched between films, so it does not come into direct contact with air and does not oxidize in this state. However, if it cracks due to repeated bending, air will get in and the material will oxidize, causing a decrease in performance.

QIs it okay to fold the EMS card?

APlease be careful not to bend it repeatedly as it may crack or tear.

QHow many grams does an EMS card weigh? If the size is too large to fit in the card pocket, can I cut it up and use it?

AIf the size does not fit, please cut it with scissors or something similar, leaving a space of at least 1mm between the main body and the laminated pouch.

QThe magnetic field of the bank cards and passbooks in my wallet, as well as the passbooks and cards I keep with me, is getting weaker, and I'm getting fed up with having to visit the bank again and again during business hours. Will storing my passbooks and cards together weaken the magnetic field?

ACustomer information data is recorded on the magnetic tape of bank passbooks and cards. If a strong magnet is applied to the magnetic tape, the data will be lost or become unreadable. If the magnetic tapes of passbooks or cards are overlapped, the magnetic tapes may interfere with each other and data may be lost. By placing an EMSsheet between the passbooks and cards, the magnetic tapes can be prevented from interfering with each other, preventing data loss.

QIf I store multiple bankbooks or cards between two EMS cards, will the magnetic protection still work? If I place multiple bankbooks or cards between two EMS sheets, will the magnetic strips interfere with each other and weaken the magnetic field again?

AIf the cause of data loss is interference between magnetic tapes, storing multiple bankbooks between two EMS cards may result in data loss. If you store the bankbooks in a way that prevents magnetic tapes from overlapping, you can prevent interference between the magnetic tapes, so it is a good idea to store the bankbooks one above the other.

QHow many bankbooks or cards can I store on an EMS card and still have the magnetic protection effect be effective?

AAs long as the magnetic strips do not overlap, the magnetic strips are effective no matter how many there are. If there is a risk of the magnetic strips overlapping, you will need to place the EMS card between the passbook or card.

QIs the electromagnetic wave and magnetic field protection effect effective for about two years as stated on your website?

AThe warranty period is two years, but performance will not be affected unless the lamination film is damaged. If the lamination film is damaged and the EMS card itself cracks, performance will be affected.

QWhat devices are at risk of data loss due to magnetic fields?

AExamples include the speaker parts of mobile phones, magnetic health devices, clasps on handbags, clips and hooks with magnets, magnetic necklaces, and audio equipment such as radios, televisions, and stereos with built-in speakers.

QIs it possible to put an EMS card between my SUICA and ICOCA cards and use them on the front and back of one pass case? (Normally they cannot be used together.)

ADo not put IC cards such as SUICA and ICOCA together with EMS cards in the same pass case, as this may cause reading errors for the IC cards. EMS cards have high skimming prevention capabilities, so even just putting them together may cause them to become unreadable.

QIs this product fire resistant, fire weak, or flammable?

AMetal materials are highly heat resistant, so there is no problem. The film is also made of polycarbonate, so it can withstand heat up to 200°C, so there is no need to worry about it catching fire in everyday life environments.

QCan EMS cards be used with any magnet to prevent data loss on cards and bankbooks?

APlease note that if you bring your card within 3 cm of a bag or pouch clasp that uses a strong magnet, data may be lost even if it is protected with an EMS card.
