Credit card for Singapore + UK

I have recently started a full time job earning approx 50K year I am hoping to apply for a starter credit card and hopefully a supplementary card as I will be giving it to my sister who is going for exchange to the UK

Does anyone have any good recommendations on what card would be best? I don’t spend alot I live with my parents so no bills, this would be mostly for fraud protection, online shopping, travel and my sister to use on her exchange to UK
