Well, I don't have the cb card with me to evaluate but by poor quality I assume that it is flexible (not rigid), lightweight and has poor print quality.Need your validation here @plastikman
Polyvinyl Chloride is the plastic used to make cards. It's properties can be varied by changing the initial formulation.
So, it isn't right to blame the plastic per se but only the cost cutting practised by sbi. The print quality too depends on the quality of printing employed.
I personally like the embossed details in place of laser etched details.
