Any other card machine
clunk 6/10
You key the total in by hand.
A standalone EFTPOS machine Ragpiq has never met. Build the cart in checkout, type the total into the machine, and choose Mark as sold once it approves. Credit and discounts still work, because the cart is Ragpiq's. The typing is the clunk.
If the machine came with Square, Lightspeed or Shopify, connect it instead: see Point of Sale for what each one can do.
