Challenge is flawed - if long term backup is important you need to physically secure both your storage device and it's reader together. You can't count on the device being usable on devices in the future.

For example the voyager golden disk had instructions on how to construct the device to read it written on the disk itself visually.

So what you would do in your case is store the memory card with say a laptop (battery removed) and a charging cable.
