How would we solve this problem about payments

[cafter]

I figured out a important point in taking crytpo as payment methods,
let you have given a customer a $101 worth of goods, then he paid you $101 in bitcoin ok
than 5 customer comes and 5 of them purchase goods worth $46, $108, $106, $89, $100, respectively ok then those all pay you via bitcoin in price of that time of one bitcoin
than sometimes later like 3 hours later, you think that one women's payment is missing you have bill but there is many transaction(in your phone or the address you used to take payments from customers) of bitcoin like 10 to 20 transaction then how would you figure out that the women had paid you payment or not, because that time the bitcoin price was different and now is different , and seeing only address doesn't tell you name of the person or face of the person.

If you are charging a person in dollars then your transactions should also be denominated in dollars so that they get the same amount of money refunded (albeit in different amounts of BTC).

And if the price is denominated in Bitcoins then there is no question about the dollar value of something.

Name, address of a person is something credit card companies collect. Crypto payment gateways also ask users to supply that information - and that is without involving KYC at all.

How are you accepting payments from users? Do you just generate an address and give it to people? If you can give more details on what you're trying to achieve, we might be able to give you better alternatives to work with but it looks like you should use a payment processor and generate a unique address for each user/invoice.

What it can last ended to is for the woman to provide you her txid which is enough to prove her payment. About the price fluctuation, you should know that you are dealing with a volatile asset and only little difference in price would likely be seen after the payment has been initiated. For business, it is better to make use of a payment processor, especially if you are having many customers that are paying with bitcoin, payment processor can even auto convert it from bitcoin to fiat for you.

and seeing only address doesn't tell you name of the person or face of the person.

you can always ask for TX address from buyer before preceding each transaction. To confirm if its the right amount you can use a simple api that check price at a date of transfer. you can also set a price in bitcoin just like many crypto/fiat transaction intermediaries work (like bitpay or coingate). when you click "pay with bitcoin" it check current bitcoin price, set a price in bitcoin, add a fee, generate new bitcoin address for deposit and wait.

You must be clear about it.

- Exchange rate at time of payment. Where is the rate source? From Binnace, Coinmarketcap, Coingecko, Bitfinex, BitMEX ?
- You can credit each receiving address and label it with name of each customer if necessary. But this will increase your inputs for future transactions, then eat you more trasnaction fee.
- Did you wait for one confirmation before processing goods to your customers? If it is what you did, you should have a transaction hash for each customer. Note it in your sheet.

If you don't wait for 1 confirmation at least, it is risky. Double spend or reorganization can occur.

How many confirmations is enough?

Have you ever deposited bitcoin to an exchange? If so, have you ever asked yourself how they know the deposit has been made by me? Exchanges give a new address to each of users and that's how they can know who has made a deposit.
If you have a store and want to accept payments in bitcoin, you can do the same thing.

There are a few payment processors you can use for this: https://bitcointalk.org/index.php?topic=5259548.0;topicseen

If you can't afford the 1% fee that most payment processors have, or to run your own BTCPayServer. You can maybe look into coinos.io. I haven't really used them myself (aside from testing) but it's pretty simple and straightforward. You create an account and click "request payment" whenever a customer wants to pay in BTC, a unique LN invoice/bitcoin address is then generated for the customer. If he pays, a message will show.

You can also check this video to see how it works: https://www.youtube.com/watch?v=LXduj4fnSuw

If your store is small, you can manually do this with Electrum wallet

This
https://bitcoinelectrum.com/how-to-use-the-electrum-receive-tab/

and that

I'm a bit new to electrum and pondering now on how to create QR code for receiving address which is in the list of available addresses. Is there any possibility to do this internally in  Electrum itself ?

You mean the addresses in the "Addresses" tab?

In Desktop Electrum: Right-click on the address of your choice, select "details"; then click the QR code icon near the address (above);
A QR code of that address will be displayed.
This button:


In Android Electrum: Go to 'Menu/...->Addresses', tap the address of your choice, then tap the green highlighted address and the QR code will be displayed.

One of the main challenges in accepting cryptocurrency payments is that once you get them there is no way to reverse the transaction and it is very different from a credit card. Because coins are worth different amounts at different times and depending on how fast or slow the transaction is going they may or may not get back all the coins sent to them.

The solution is to enter the price of your service or product at the current BTC price. So that if there is a payment error at a later date, you can easily check it using a password, but with several customer payment options such as cellphone bills and credit card debit cards.

Very complex things have been easily solved by technology. What's been asked by OP is simple thing, each transaction shows the value at the time of transaction and the value at right now. This is more than enough to understand which transaction is done by specific person.

[odolvlobo]

The solution is to use a different address for each payment.

[D ltr]

actually the payment is successful or not can be seen from the txid provided,
it's the same when we complain about the exchange of funds, we don't include the txhash that we always ask at first
and you can provide a unique code for each payment that will be made

[benalexis12]

I don't really understand what you're saying, the only thing I understand is that there are 5 customers who bought bitcoin in different
amounts, right? now, the question is of course is there a charge or transaction fee? Then it is normal that your purchase of bitcoin will be
based on its current value in the market because it is volatile. Now, what do you want to imply in this topic you made?

[hosseinimr93]

actually the payment is successful or not can be seen from the txid provided,

Providing transaction ID wouldn't be enough if the same address is given to different people and especially if there are many customers.
I can simply search for the address on a block explorer, pick the hash of an incoming transaction and claim that I have made that transaction.

The simple solution is to give different addresses to different people.

OP isn't talking about people buying people. He/she is talking about people buying things and using bitcoin as payment method.

[rat03gopoh]

If you accept bitcoins, you should tolerate the volatility, then your reference is simply the amount of bitcoins the woman owed at that time and you should prepare a receipt with the billed amount of bitcoins in bold and some customer details including a txid to prevent confusion.

There are many of these solutions, depending on the goods you're selling and what the payment mechanism is. Some types of goods also allow you to get the tx confirmed before the goods are taken away, for example goods must go through a packaging process of up to 20 minutes.

[TribalBob]

simple solution always give new address to different customers if there are multiple concurrent transactions .
or you can give a unique code for each payment to each customer like other online stores and I often find it when making payments

[Synchronice]

than sometimes later like 3 hours later, you think that one women's payment is missing you have bill but there is many transaction(in your phone or the address you used to take payments from customers) of bitcoin like 10 to 20 transaction then how would you figure out that the women had paid you payment or not, because that time the bitcoin price was different and now is different , and seeing only address doesn't tell you name of the person or face of the person.

Don't get me wrong, you have to use Then instead of Than in this case. Then means after something and than means comparison.

If transaction is missing after 3 hours, you will see it as unconfirmed transaction or transaction with less than 6 confirmations if you visit blockchain explorer and see transaction in details. If I were you, I would set up digital screen where I would generate QR code for them and would provide them with converted USD to BTC amount and with live information of recommended bitcoin transaction fee and would manually check fee of each transaction to be sure.

I assume touchscreen and laptop will help you to make this process more exiting and smooth. You will be able to handle things more professionally.

You can check the USD value at the time of transaction on Blockchair.com, you don't have to worry about that.

[~snipped~]

It's kinda pretty simple if I understood the context of your post correctly. Since your business is the busy type it will be safer for you to generate new unique for each transactions that way you can easily identify whoever didn't make their payment rather to go through the stress of using Blockchain explorer trying to check each transaction id

And we have a lots of wallet that does that for example you can use Electrum which is an open source wallet and also you can have multisig wallet with it.
