a clean light create an infographic illustrating the micropayment system in the travel industry. The design should feature a streamlined, easy-to-understand flowchart showing the process from booking to payment. Start with a user selecting travel services on a digital platform, moving through various microtransaction points like choosing additional luggage options, selecting seat upgrades, or adding on in-flight meals. Each point should have a simple icon representing the service, connected by arrows to a central wallet symbol showing the seamless flow of small payments. Use a professional, muted color scheme to convey a sense of trust and efficiency. Include brief labels and minimal text to maintain clarity and focus on the simplicity and convenience of micropayments in enhancing travel experiences."
