Can my employer view the transactions the I make?

This depends on whether you have an Employee Benefit Card or a Business Card.

Employee Benefit card:

No, your employer cannot view the transactions you make as those funds are personal and can be spent at your own discretion.

Business Card:

Yes, your employer can view the transactions made on the card. As this is a business card provided for expense purposes, it is designed to allow employers to monitor and reconcile expenses incurred on behalf of the company.
