Problems with Plastiq Payments on Personal Visa Credit Cards

Plastiq, the online payment processing system that allows you to pay bills that you otherwise could not pay on a credit card for a 2.5% fee, is having trouble with many  consumer Visa credit cards.

2.5% Cash Back Everywhere With New Alliant Visa

Alliant Credit Union has come out with a new cashback credit card that offers 3% cash back on all purchases for the first year of card membership and 2.5% after that.

The only other cards I'm aware of that earn the same or a better cashback rate longterm are limited to a small market. They are the:

USAA Limitless Cashback Rewards card, which earns 2.5% (w/no annual fee) on all purchases. See who's eligible to become a USAA member
Marukai Premium JCB Card which earns 3% on all purchases (w/low $15 annual fee).

The issuing bank is Citi for both cards.
