The process is very straightforward but one must take care, whenever attepting an online transaction of any sort. Currently, more than half of all purchases are carried out over the internet. Online shopping is convenient and easy, meaning that more and more citizens are turning to this method instead of facing the crowds in the malls. The internet also enables people to do better analysis and grab the top deals. Nonetheless, there still is a shadowy side to e-commerce. Here are the vital rules, one must follow. Always purchase from home. Criminals can easily access sensitive information when you take advantage of non-private wifi connections, which means it's safer to purchase from your living-room than in retail premises. Do not make purchases when connected to bus stations, hostels or any kind of public hot-spots. Avoid Twitter/FaceBook offers. You cannot rely on these types of offers as the majority of links are abbreviated. This means you cannot be confident that the link takes you to a proper website. Buy with a credit card. Never use a debit card. More than 50% of debit cards require that acts of fraud be reported in less than 2 days to get limit liability. Don't wire money to companies. It's impossible to get your money returned when you do this. Make sure you check credit card statements. Put online receipts inside a secure email folder, then you may crosscheck payments. Never provide any excess information. There's no need to give out your driver's license number. They shouldn't ask your social security information either. Should any company demand this info, be suspicious. Choose long passwords that you still can recall. If your computer to store the password, always select 'No'. Should someone else gain access to your device they could find your credit card details. Don't get caught out by gift card cons. If you receive an email and it says you've qualified to receive a gift card but then asks for your credit card details, delete it. Legitimate retailers will not request private financial data. Always remember this, because it's important that customers remain cautious when shopping over the net. Buy from home and be certain that the company is trustworthy.
