Sorry for this question, which may be very basic and silly! I am working on my Square Online website for my jewelry designs, but it's not ready yet. I'll be selling unique, one-off items at a craft fair and want to use the Square magstripe reader to take credit card payments at the fair. Those one-off items are not in my Square inventory, since I won't ever sell them again after this fair, and it would be a huge amount of work to list them all in the inventory prior to the fair. Can I still use the magstripe reader if the items I'm selling are not in my inventory? Thanks!
