I see the value of cashu as a merchant because there are very few customers who pay with sats. It requires a lot of management to keep lightning liquidity balanced for an occassional in person payment. Now with Zeus POS + cashu + Square I have an integrated inventory system where staff can ring up customers like normal, have my inventory pulled, the customer can scan qr code, get a normal receipt and we receive payment without fussing with liquidity. The customer can use ecash or their own lightning wallet as we are presenting a lightning invoice qr code. Then we can sweep the ecash from the mint into a lighting channel on Zeus at the end of the day hopefully reducing fees.

but do you currently accept token from any mint or from a whitelist? that is the main thing I couldn't get my head around. it sounds like the cashu devs are working on a swap mechanism for wallets so that this is seamless for the user.

I think the main thing to consider is that the sender is scanning a lightning invoice qr code from our mint of choice. They can be spending from any mint or from their lightning balance. The sender pays a ln invoice created by the mint we choose, which then issues us the ecash. We aren't getting sent raw ecash tokens from various mints! The mint has to maintain the liquidity we just get paid and withdraw as we please.
