ANEX 3 或 4 但 只用 BBP and BonVoy biz，
Chase 7 或 8 use them only for their category bonueses or when there are Chase Offers, except CSP the rest are all zero AF with good benefits. 4 of them are UR cards, the rest are mileage / hotel point cards.
CapOne 1，非常古老的, 从 Ancient Venture卡 was still a Mastercard, more than 10 years ago? 降级到这个 zero AF 版本。Used once a year to keep it active.
