BPI Express Start 2021 (19-year-old applicant)

Hi there! This blog post will share my experiences in applying for a BPI Express Start (BPI Secured Credit Card). I will discuss first what does that mean. BPI Express Start is the easiest way to get a BPI Credit Card without any income documents. Yes! It is easy to apply, and you don't need any ITR or business documents to provide since the bank will ask for a holdout deposit, or we can call it as collateral. This program is best for low-income or first-time earners, with default card/s, freelancers, students, and more! The main reason I applied for it is to build my credit history while still in adolescence. I am only at the age of 19 from the time I apply. What are the requirements to apply for a credit card via BPI Express Start?  - Must be at least 18 years old - Must have a business or residence contact number - Completely filled out and signed Express Start Application Form - Completely filled out and signed Deed of Assignment (Blue Form, it is used to authorize BPI for the
