The world needs an app that helps you check out faster

I will often find myself in a long line at the grocery store, the checkout line, etc… When I am waiting in line, I can’t help but think “there has got to be a better way.”<br><br>My idea is for an app that the customer uses and one that the cashier uses. When the cashier finishes scanning someone’s grocery items, they input the number of items they’ve scanned into their app. That number is then sent to the customer’s app and the app knows how many items the customer in front of you has.<br><br>The app can then calculate the time it takes for the cashier to scan one item and calculate how long it will take them to physically put the groceries in their bags.<br><br>The app then knows how many grocery items are behind you and can calculate how long it will take for the cashier to scan each item and put them into grocery bags.<br><br>Therefore, you have a total number of time until the cashier is finished with the person in front of you and is ready to start scanning your groceries.<br><br>When you look at the app, it knows how many items are in front of you and can estimate exactly how long it will take for the cashier to scan each item and put them into bags. It also has a real time view of exactly how long until it will be your turn. The app shows the line number with the number of items that are in front of you in each line.<br><br>In other words, you whip out your phone while you’re waiting in line and go to the app, enter the name of the location you’re at along with the line number and the number of items in your cart. You then have a list of all the lines along with how many grocery items are in front of you in each line and also an exact time until it’s your turn.<br><br>You can then choose to go into the line with the least amount of items behind you.<br><br>I imagine the app to do a few more things in the future. It also could send the customer the total cost of their groceries instantly, the line number, and the number of items in front of them and an estimate of how long it will take until it’s their turn.<br><br>It can then also send the customer the video of the cashier scanning each of their items along with the total cost of groceries.<br><br>The cashier could also put the number of each line into their app and it could send a notification to the customer when it’s their turn.<br><br>Each item that you have in your cart could also be entered into your app and you could input the number of items that you have for each item you have. You could input 3 apples, 2 oranges, 4 bananas, etc…<br><br>The app could then send the customer the exact total cost of their groceries as you enter each item.<br><br>I believe this app would also provide a real world use case for the blockchain as well. This app would allow the customer to be in total control of their groceries and the cost of their groceries. It must check out with the store but it also must check out with the customer’s app.<br><br>Since the customer’s app has a video of the cashier scanning each item, the customer can instantly tell if the cashier has scanned an item twice, or if the cashier is trying to charge the customer double for each item.<br><br>Each grocery item has a unique identifier in the app. This unique identifier can be used and acted as a block in the blockchain. Each time an item is scanned, the unique identifier can be used to create a block. Each block can then be used as a unique identifier the next time that item is scanned. This creates a chain of blocks or a blockchain.<br><br>The app could then send a notification to the customer if the item is scanned twice, or if the price of the item is more than the price in the app.<br><br>The app could also send the video of the cashier scanning the item and putting the item in the bag directly to the customer’s phone. The customer can then verify that the item was scanned properly and that the price for the item was correct.<br><br>The app could also send a notification to the customer if the total number of items scanned do not match the number of items in the grocery cart.<br><br>The app could also send a notification to the customer if the price of the groceries do not match the price in the app.<br><br>The app could also send a notification to the customer if the video of the item being scanned does not match the item in the app.<br><br>Therefore, the app has multiple checks to verify that the customer is being charged correctly and that the customer is receiving exactly what they paid for. The app can then also send a notification to the cashier if the customer is being charged incorrectly and if the customer is receiving the wrong number or wrong type of items.<br><br>The app of course, must require the customer to put in their app the number of items that they have for each item they have. This app must check out with the cashier, but it also must check out with the customer’s app. The customer’s app then knows the price of each item and the number of each item in the customer’s shopping cart.<br><br>The app must also be able to know exactly when the cashier has finished scanning an item and has moved onto the next item. This could be done using AI and video from the camera on the customer’s app and/or on the cashier’s app. When the item is placed in the bag, the camera on the customer’s app could know that the item has been placed in the bag and it could also tell what item has been placed in the bag. The app could then send a notification to the customer if the item in the bag does not match the item in the app.<br><br>The app could also use the camera to tell when the cashier receives payment from the customer. This could also be done by using the camera on the customer’s app and/or the cashier’s app. When the cash register closes and the receipt is printed, the camera on the cashier’s app could know that the customer has paid for their groceries and it could also tell how much the customer paid for their groceries.<br><br>The app could then send a notification to the customer instantly if the amount that the customer paid for their groceries does not match the total price for their groceries in the app.<br><br>This is a multi-billion dollar idea that could be implemented almost instantly in every single grocery store, every single checkout line of every single store on the planet.<br><br>I am in the process of getting a patent for such an app. I just wanted to post this here as I feel it is a brilliant idea.
