I got a secured credit card while opening dollar and peso savings accounts back in January, primarily to get the wife a supplementary card for her to use in emergency. Unfortunately, she's since encountered quite a few "emergencies" every month at various stores in the malls. Anyway, credit line was 80% of money held in a secured savings account, and no interest if paid in full by due date.
In the Angeles City S&R recently, there were HSBC sales staff approaching customers to apply for their credit card. For foreigners, they do require 1) a PI government ID, like PI driver's license other than ACR card, 2) have to have had a "local" credit card as a primary holder for a year and 3) Visa and visa "number" which most of us don't have whether a tourist or balikbayan.
