square now lets us merchants accept bitcoin via their pos app—scan a qr code at checkout for instant, low-fee payments over lightning network. sign into your square dashboard, enable bitcoin payments under settings (it's rolling out, so check availability), and process like any card sale with zero extra fees.
Might be worth keeping this bookmarked to share.
