Amazon check cards and gift cards are two different Amazon services, and they have the following differences:

1. Different functions: Amazon check cards are a shopping tool that cardholders can use to purchase goods, which is equivalent to ordinary credit cards. Amazon gift cards are prepaid consumption tools that cardholders can use to redeem gifts or purchase goods on Amazon, but cannot be used for cash consumption.

2. Different values: Amazon check cards have a certain credit limit, which is determined by the bank and can be used when shopping. Amazon gift cards have no credit limit, which is equivalent to cash recharge and can be used without restrictions.
