Receive Payment in
Auto reference (VS) for multiple payments Variable symbol, reference code for payment tracking. To track your payment we add 4 digits to the end of the amount, for example, in USDT on the Tron blockchain, 6 digits after the decimal point. The first two are used, for example 10.55 (10 dollars 55 cents), and the value with the addition of the variable symbol would be 10.550001. In fact, this is 1000 times less than one cent, the buyer does not overpay. But you can trace his payment.
When you use up to 10,000 codes in Merchant mode, you will be automatically added a new USDT address that will hold the next 10,000 codes and so on ad infinitum. This feature will allow you to serve even a large online store with thousands of orders per day.
Otherwise, you would have to use a separate address for each payment. And then pay a blockchain fee for collecting all the funds in one address. For example, if you have 100 payments on 100 addresses, in order to raise funds to one address (for exchange, etc.), you would need to pay a commission 100 times (0.9$ per one). We got around this shortcoming with the elegant reference numbers described above.
