All Chase business cards that earn Ultimate Rewards points have the work INK in their name. Mentioning INK alone does not identify the specific card. Chase sometimes inserts the word "business" in the name, but this is redundant INK = Business.
In addition to those listed in the glossary there are three discontinued INK cards: INK Bold, INK Classic and INK Plus -and- a newly announced card INK Unlimited. Most INK Bold and INK Classic accounts have been converted to another type, but many people still hold INK Plus.
Huh. I've always used "Ink" by itself to refer to what I thought was the default Ink card, and would use 'Ink xxxx" for other cards.. But in this case "always" means since Dec '17, which is when I got the card. I didn't even realize my Ink card was Ink Cash until I looked it up yesterday. Putting this wiki together is helping me learn a thing or two. Making corrections now.
