How does a prepaid card work?

The prepaid card looks similar if not identical to the credit card. I mean this is a piece of plastic, standard size, with a magnetic strip on the back.
However, their operation differs mainly credit card by the fact that the user makes the payment of the card in advance. I mean the card is bought before purchasing the product (s) and / or service (s) for which you intend to use the prepaid card.
Another difference to the credit card is that the prepaid card is an anonymous card. The prepaid card does not carry the name of whom the purchase and that having made the payment in advance issuer of prepaid cards do not require any further collection activity, as it happens in the case of credit cards. This represents a great advantage for those who are not comfortable revealing personal information especially when it comes to operations over the Internet. Although today the security measures to prevent fraud in this regard are very sophisticated, undoubtedly the prepaid cards will always have more advantage and grant peace to their users regarding credit cards, at least in regard to theft identity.
Prepaid cards also allow greater flexibility in the available balance thereby reduces the risk of being overtaken by a high amount of money by the unscrupulous. While the credit card processing results in a cumbersome and often impossible to adjust our line of credit to our real and immediate needs in the case of cards one can acquire the desired amount, or very close to him, almost that on any day, any time.
Another advantage of prepaid cards versus credit cards do not require a bank account or credit history to buy them because the advance payment be made to the CA is not interested in confirming whether the customer or user of the card is a good payer. In fact, these cards were originally designed for Internet commerce where the biggest market is represented by mostly young people who still do not generate a steady income and stable and therefore could hardly get a conventional credit card.
Prepaid cards today operate globally and virtually all businesses where credit cards are accepted. An additional advantage, especially for those who are not very orderly in their expenses is that their normal consumption limits are lower from the fact, as mentioned before, that are normally purchased for the acquisition of a particular product. This will avoid "surprises" at the end of the month with a receipt for expenses that can not possibly afford.
