What about the supplementary card given by my husband? His mobile phone will also have what he bought.

The supplementary card given by my husband, where to buy things, there will also be consumer information notification in the mobile phone.

Every consumption of the secondary card is included in the bill of the main card, so the cardholder can know the consumption of the secondary card at any time, which means that the secondary card may receive text messages when consuming the main card. The key to this possibility is to look at the amount of consumption. At present, although many banks open SMS service reminders by default, except for platinum cards and high-end cards, ordinary credit cards (such as Puka and Gold Card) are required to send SMS notifications when their spending amounts reach 500 yuan or above, and they will not send SMS messages when they are lower than 500 yuan, and the same is true for the main and secondary cards.

Supplementary card is a kind of credit card for natural persons who are over 0/3 years old and have the capacity of restricting civil conduct. All expenses incurred by the supplementary card shall be borne by the cardholder of the main card, and the cardholder of the main card shall be required to return the bill expenses incurred by the supplementary card.
