US Patent 11880813 Money transfer by use of a payment proxy

In some examples, a payment system generates, for a first user, a proxy identifier having a syntax including a symbol and a string of one or more characters that are concatenated such that the symbol appears immediately before the string. The proxy identifier is associated with a financial account of the first user. The payment system receives an indication of an intent to transfer funds from a second user to the first user. The indication includes the proxy identifier in lieu of financial account information of the first user, and to identify the financial account of the first user for receiving the funds. Based at least on identifying the proxy identifier, the payment system accesses the financial account information of the first user and initiates the transfer of funds from the financial account of the second user to the financial account of the first user.
