Solayer's Emerald card comes with a feature that is quite useful for most U-card users: daughter cards.
Ability to create an unlimited number of sub-cards under one account for free. Then set a separate label and spending limit for each sub-card to meet your different consumption/spending scenarios:
➡️ Create different sub-cards to correspond to different types of expenses, for example, one for utility bills and one for e-commerce shopping. The advantage of this is that it is very convenient to count and classify expenditures;
➡️ In some trading scenarios where you think it is risky or unwilling to expose the main account, you can temporarily create a separate sub-card to trade, and throw it away when it is used up;
➡️ Create a subcard for family and friends, and you can set different spending limits.
Each card can also earn Emerald points separately to obtain airdrops or benefits.
