This is just additional information.

The asker specifically mentioned: para que los invitados como regalo les depositen dinero. So I think "cash" needs to be mentioned, as the intention is to get money, and not gifts from a store or list.

In the US, people normally use wedding registries.
A bridal registry or wedding registry, is a service provided by a website or retail store that assists engaged couples in the communication of gift preferences to wedding guests. Selecting items from store stock, the couple lists desired items and files this list with the chosen merchant. The list is then made available to wedding guests, either by the couple's family or by the merchant. Upon the purchase of a listed item, the merchant updates the gift registry accordingly. In addition to providing valuable information for the buyer, the system helps prevent the receipt of duplicate or unwanted gifts, potentially saving time for both giver and recipient.
