To securely accept online payments, it's important to focus on three things: secure payment methods, data encryption, and trusted payment platforms. Never accept payments directly through dubious services or manually process card details—this immediately increases risks.
These days, it's easiest to use ready-made solutions with built-in security. For example, Carteza is a platform that allows you to accept payments quickly, securely, and without hidden fees:
