X-ray resistance

Compliant with ISO7816-1

The data will not be affected by X-ray baggage inspection at airports

UV resistance

Compliant with ISO7816-1

The memory card body is made of a resin that does not allow ultraviolet rays to pass through and has no effect on data

Electrostatic resistance

Nextorage’s original anti-magnetic test: put the memory card on a strong magnet (2,500 gauss: equivalent to approx. 30,000 times the strength of the electromagnetic field emitted by a typical microwave oven) for 70 hours. That means there is no effect even if the card is close to a magnetized household appliance
