Hello,

Many of us works with mobile phone applications like Yzer app or similar tricks that pays with BTC LN invoice.

Use of wallet like Muun or similar is full of fee means you generate invoice with application to receive money then you generate once again to deposit to website with BTC LN invoice.

Use of qr code reader after generate invoice with goqr me will set invoice uppercase means invalid invoice.

The remaining solution is having Whatsapp Messenger in both of PC and mobile phone.

You send message to yourself with generated deposit address then you copy this and paste to Yzer app or similar applications.

This method works without fee except cellular mobile data.
