Can a government agency apply for a credit card under its name and use it to purchase goods/services?

Government Procurement

Q: 1) Are we allowed to use credit card on office purchases less than 50k e.g. tv, aircon etc. 2) is there such thing as corporate credit card? Kuha ka ng credit card under the name of agency. Then yung bill ang basis mo para bayaran thru ADA. Is this allowable by COA? Any legal basis for these?
