Plastic gift cards have become ubiquitous in the modern retail landscape. They're not just a means to give someone a monetary gift; they're also a powerful tool for businesses to increase sales, loyalty, and brand awareness. But how do these little pieces of plastic hold information, and how do they work? Let's delve into the technology behind them.
From traditional magstripes to state-of-the-art EMV chips and NFC capabilities, modern gift cards ensure that the shopping experience has never been easier or more secure.

A magstripe, or magnetic stripe, is a band of magnetic material on the back of the card that stores the card's information. When the card is swiped through a card reader, this information is read and processed. On the other hand, an EMV chip, commonly known as a smart chip, is a tiny microprocessor embedded into the card. This chip securely stores data and requires the card to be "dipped" into a reader, creating a unique transaction code for each purchase. EMV chips offer enhanced security compared to magstripes, making them more resistant to cloning and fraud.
In general, QR codes and barcodes on gift cards are primarily used for quick scanning and do not have the same security mechanisms as magstripes or EMV chips. While they can quickly relay information about the card's balance and other details, they lack the encryption and unique transaction features of more advanced technologies. That said, many gift cards with QR codes or barcodes also include additional security features like PINs or CVVs to enhance security during redemption.
Not all card readers are equipped to handle NFC (Near Field Communication) or RFID (Radio-Frequency Identification) transactions. To use the contactless feature of a gift card, the merchant's card reader must be NFC or RFID compatible. However, as contactless payment becomes increasingly popular, more and more merchants are upgrading their systems to accommodate this technology. If in doubt, check with the merchant or look for the contactless symbol on their card reader.
