Essentially similar - I think its about credit usage. Initially it is a little of of a chicken and egg situation.
Most of the time, the bank that processes your payroll should be able to give you a basic credit card (unless you're with some random third tier local bank) to get you setup. After that, put as much of your regular outgoings on there - internet, phone, octopus reload, grocery shopping etc on your card and pay off in full.
Also, best to approach the credit card promoters - usually at major MTR stations like Admiralty or elsewhere... they will help you fill up the application "correctly" and have some sort of commission tied into your approval (as opposed to the fuckwits at bank branches who are more than often just trained to say "no cannot").
This thread is almost encyclopedic in terms of information about credit scores...
