Payments may be made electronically using a credit card or fund transfer.  I use SquareUp to process payments and schedule appointments. SquareUp meets the high standards of HIPAA and the banking industry for security and privacy with regard to financial transactions.  However, SquareUp may send, automatically or per your request, email or text message receipts that reveal personal health information such as the date and type of lactation visit.   If you are not comfortable with this, payment may be made via cash or check instead and appointments may be scheduled via text or phone call.
