Zeo sd vs bluetooth

I want to buy used zeo. But newer model uses bluetooth and I’m concerned about bluetooth near my head during night. So older 101 uses sd card reader. How do I read and look at results next day?

I only used the older Zeo for a month some 9 odd years ago, so my memory is hazy, but that version has a screen on the front of the charging station which allows you to see your data the next data.
