No matter which bank's credit card, you can accumulate points as long as you spend, and Citibank's credit card is no exception. If the landlord doesn't know his credit card points accumulation, he can inquire in the following ways:

1. The landlord can find his points directly on the paper bill.

2. The landlord can call Citibank's credit card customer service hotline, and then turn to manual service to check his consumption points.

3. Or the landlord can log in to Citibank Online Bank and inquire about the accumulated credit card points of Citibank in the column of credit card points insertion.

The above is the information I know, I hope my answer can help the landlord!
