Which of these 2 readers do I use?

I have a white squarish reader for my phone and a dark blue triangular reader. Which do I use. I was sent both.

Hi @Carolyn88! Welcome to the Community.

You can use any reader that works best for you. Although- I'm not entirely sure of what the blue triangular reader is? We don't carry anything like that I'm aware of.

Can you possibly send us a photo of it?
