Members of the 850 Club can be broken into two groups. There are the super-knowledgeable tacticians trying to crack scoring algorithms, and the naturally prudent. Some are prepping for a loan. Others are just credit-score hobbyists. Paul Chua, 40, who works at San Carlos, Calif.-based Helix, a startup focused on personal genomics, is one of the tacticians.
A quick Google search yielded this terms and conditions sheet, which may be slightly different than the one you’d receive if you applied for a card. According to the one we found, Credit One charges an annual membership fee from $0 to $99. Credit line minimums are between $300 and $500. So you could be paying $99 for a $300 credit limit. APR is relatively standard, but on the high side, with variable 19.15% to 25.24%. Given the high annual fees, we recommend saving your money and using a secured card with no annual fee to begin rebuilding your credit score.
