FYI - your Credit Union and your Credit Union’s Credit Card are likely two separate and unaffiliated companies. Most small to mid sized banks and credit unions don’t actually issue credit cards. They contact that out to the credit card arm (ex. FIA Card Services) of a national bank (ex. Bank of America) that offers white-label/rebranded cards.
If you just need a scanner to get and clear the codes, grab the cheapest one you can find. No point in spending the extra money on one that connects to the Internet and/or diagnoses your codes if you are mildly competent at using a search engine yourself.
