These new tools, like Bitcoin Lightning, help store owners by getting rid of the slow and "hidden" parts of old banking. And they are getting rid of the fees. They will adopt a new, faster, cheaper system.

Here is how they make shopping faster and save money:

1. Stopping "Middleman" Fees

When you use a credit card, a "middleman" (like a big bank) takes a small piece of the money. Usually, they take about 3 cents for every dollar.

• The New Way: Bitcoin Lightning doesn’t need a big bank in the middle. The fee is tiny—usually less than a penny.
• The Result: If a store sells $1,000 worth of stuff, they keep $30 more than they used to. That adds up to a lot of extra money for the store!

2. Instant "Final" Payments

With old cards, the store doesn't get the money right away. The bank just promises to send it in a few days. Sometimes, the money never shows up if there is a mistake.

• The New Way: A Bitcoin Lightning payment is instant. It’s like handing someone a real $20 bill. Once they have it, it's theirs!
• The Result: Store owners don't have to wait a week to get their money or worry about it disappearing.

3. One Big "Brain"

Old stores used different machines for the register, the website, and the back room. People had to spend hours making sure all the numbers matched.

• The New Way: New tools act like one big brain. If someone buys a shirt in the store, the website knows right away that the shirt is gone.
• The Result: The store owner doesn't have to hire someone to count boxes. The machines do the boring work instead.

4. Faster Lines

Old machines can be slow when they talk to the bank. New payments take less than 2 seconds.

• The Result: Lines move faster and customers stay happy. A store that can help 10 people in the time it used to take for 5 will make much more money.
