What cards do supermarkets usually use?
    Nowadays, all kinds of cards have appeared on the market, including IC cards, ID cards, barcode cards, consumption cards, membership cards, VIP cards, magnetic stripe cards, and so on. With all these cards available, we were overwhelmed by the choice. A friend who runs a supermarket asked me, 'What card is generally best for supermarkets?' Since I am a professional in the card manufacturing industry, I am very proficient in cards, so I told my friend that supermarkets generally use these two types of cards.

1. Supermarket magnetic stripe card
    Generally, if a supermarket doesn't have special needs, using a magnetic stripe card is enough to handle all the customers, because the main functions of the magnetic stripe card are consumption, points, and discounts. As long as customers show their magnetic stripe card after making a purchase, they can enjoy these discounts. One downside of magnetic stripe cards is that they are easy to demagnetize. Once demagnetized, the magnetic stripe card becomes unusable. So how can you avoid demagnetizing magnetic stripe cards? You can check the informationCauses of magnetic stripe card demagnetization and how to prevent demagnetization

2. Supermarket smart cards
    Supermarket smart cards mainly refer to IC cards and ID cards. IC and ID cards do not have demagnetization issues, which is their advantage. Additionally, they are more convenient than magnetic stripe cards. You only need to swipe gently in the sensing area of the IC card reader to enjoy discounts, points, and consumption discounts provided by supermarket merchants. Moreover, these smart cards have an especially long lifespan—generally 7 to 8 years without much problem, which invisibly saves supermarkets a lot of costs. So when people ask me which card to use in supermarkets, I usually recommend using the supermarket smart card.
