New iPhone, new USB-C Square Reader

[OC5Treasurer]

I have a new iPhone 16 Pro and purchased a new USB-C Square Reader.  The Square app opens on my new phone and the new Reader accesses our account.  I haven't closed the app yet.  The app required a verification code, which worked when I opened the app.  Is there anything else I need to do to swipe credit cards?   I don't want to wait until I need to use it to find out I needed to do something else.  I'd rather use Face ID on my phone to open the app if that's possible.

Thanks!

Not much you can do besides trying a Transaction.  Just be warned if you try a Credit Card Transaction you are not refunded the Transaction Processing fee.  So if you try a Credit Card, have the sale at $1.00.  

The only difference between a Cash and Credit Card sale would be that after you press Tender or Charge, I forget the wording, is you tap the cash amout or enter it as a Custom cash amount other wise you tap or insert the credit card on the reader.  I am not sure about the new ones but my readers Green Light comes on and that is when I tell my customers to insert or tap their Credit Card, this is a second or so after tapping Tender.
