What is a cardholder? What can the cardholder Bring to Desfire?

Card holder is an outer casing used to protect, organize and organize cards. It is usually made of materials such as plastic, leather, silicone, etc., and is designed with appropriate shapes and sizes for different types of cards.

The main function of the card holder is to provide extra protection against scratches, bending or damage to the cards. It can protect the appearance and chip of the card and prolong the service life of the card. In addition, the card sleeve can also help users easily carry and manage multiple cards so that they can quickly find the desired card.

In order to ensure that the Desfire card and the data on it are fully protected, it is very critical to use a custom card holder.

The card sleeve provides an extra layer of protection for Desfire cards, effectively preventing damage caused by scratches, bending or external contamination. For example, once the surface of the Desfire card is scratched, it may affect the reading performance of the card, or even make it unable to use normally. While the sleeve is designed to resist scratches and friction, maintaining the integrity and readability of Desfire cards.

In addition, the ferrules extend the life of the Desfire cards, reducing replacement costs and potential risks. Since the price of the Desfire card is relatively high, using a card sleeve can protect the card from damage and reduce frequent replacement due to card damage. This reduces replacement costs and, in critical scenarios, the potential safety risk of card failures.

Except to protection, the card holder also helps users neatly organize multiple Desfire cards. When a person needs to carry multiple cards, such as access control cards, bus cards, employee work cards, etc., the card holder provides a convenient way to centrally store these cards. Users can put multiple cards into different card slots or internal compartments of the card holder, thus effectively avoiding confusion and loss among cards.

The card sleeves made by Newbega can be customized according to customer requirements. At the same time, we also provide products such as shielded wallets, which allow users to classify cards more effectively.

How to Make a Card Holder that Suits You?

In 2020, the global collectible card game market has reached US$11.13 billion, and is expected to reach US$31.26 billion in 2027, with a compound growth rate of 15.7%. The card market is still thriving, and people appreciate the pictures and text on the cards. And keep it as a hobby.

Therefore, it is very important to protect these cards, after all, no one wants their items to be damaged.

For example, you could put a shiny collectible card in one slot, a regular card in another, and so on. This visual and neat organization makes it easy for users to find the cards they need, saving time and effort.

Commonly used materials include plastic, leather, silicone, etc. Choose materials according to usage requirements, such as choosing waterproof or scratch-resistant materials to increase the protective effect of the sleeve.

The last is to consider the design elements to make it more in line with the user’s aesthetics. For example, card collectors are more inclined to cool or brightly colored card sleeves, and they hope to be transparent, so that they can see the contents of the card sleeves clearly. Owners of chip cards (such as desfire cards) will be more inclined to its protective function, and the card holder may need to have company or team logo, contact information, personal name, etc. At the same time, design elements such as appropriate size, number of card slots, and organizational functions are selected to meet the convenience of portability and use.
