For most cryptocurrencies, the only field a user needs to specify the recipient is an address. This address can be displayed in your interface directly or encoded as a QR code. But sometimes the address is not enough for a successful payment. For example, Ripple has a concept of “multiuser addresses” which require a tag field to distinguish between recipients. Sometimes this concept is also known as the “memo” field. CryptoProcessing provides the tag field for Ripple addresses both in the merchant dashboard and in the API. In other cryptocurrencies, this field may also be known as “Memo”, “Comment”, “Label”, or “DigitalID”. When using deposits for such a currency, make sure you provide the user with both the address and the tag field. The absence of the tag field may result in the loss of the funds sent by the user.
