First, what is the "card system"?

 The so-called "card system" is to realize a variety of different management functions when the user uses the same non-contact sensor card, such as: access control, attendance, dining, consumption, parking lot access, patrol sign-in, conference sign-in, elevator use and other functions. These functions can be performed using equipment from different manufacturers,

 For example, access control uses products from manufacturer A, consumption uses products from manufacturer B, and parking lot management uses products from manufacturer C. We agree to use the same format of the card, then the user holds a card, respectively in the software of different manufacturers for registration, and has access control attendance consumption parking lot management for a variety of purposes. One card, so that customers can carry only one card to achieve a variety of purposes, reduce the trouble of carrying multiple cards.

Second，the advantages and disadvantages of the card system.

 The advantage of this mode is that the products of manufacturers with a high degree of specialization suitable for customers' own use can be selected from each function, and as long as the same type of card is agreed, a variety of one-card functions can be achieved without compatibility problems. Users can choose the best manufacturers in various fields such as access control and attendance consumption to cooperate and buy the most suitable products for themselves. One system failure will not affect other systems, and a system is improperly purchased to facilitate change and replacement with minimal loss.

 The downside: managers need to register the card in separate software. However, generally different function managers will be different, for example: attendance is managed by the personnel department, access control is managed by the security department, and dining consumption is managed by the canteen. Separate software can do their jobs instead of influencing each other.

 There are many large customers in the choice of a card, in fact, hidden "one soft pass" and "one library pass" demand.

 The so-called "hidden" is that the customer does not make it clear that he actually wants it. Therefore, it is necessary to ask the customer clearly whether he wants a card, or a soft pass and a library pass under the card, to avoid not making it clear at the beginning, and there will be disagreements and disputes in the future.

Third, what is a softpass (a library)?

 The so-called "one soft pass" is a set of software management for all functions.

 The so-called "one library through" is that all functions share a database, unified storage of various Settings and records.

Fourth, the advantages and disadvantages of the "one card + one softpass + one library pass" model

 The advantages of "one card + one softpass + one library pass" mode are: easy to unified management, registration card only needs to be registered once, new card or loss card is more convenient and only needs to be operated once, but it is necessary to authorize people in different intelligent departments to authorize and set different management software modules. By one company to provide the product, after-sales service to find one on the line.

 Disadvantages of the "One card + one Softpass + one library" model: The growth cycle of the one card industry in China is not long, and I personally think there is no company that can do all the functional modules well and integrate them together. Most of them have their own strengths, and different manufacturers have advantages in products for a few uses, while products for other uses are average or not good.

 There are also some software integration companies that buy products for different purposes from different manufacturers, and integrate all devices into a platform of one software and one library through a self-developed software. This model gives play to the respective advantages of software companies and equipment manufacturers, but there are also certain shortcomings: The company's familiarity with the products of several manufacturers is limited, the cost of re-integration is increased, and the purchase price of consumers to obtain this series of products will be increased. The close cooperation between the integration company and equipment manufacturers will affect the quality of after-sales service and upgrade of consumers in the future.

 In addition, if the software is integrated with multiple uses, the operation will be relatively complex, if the manager is just an ordinary clerk and security, the operation of such large software will be relatively difficult, and after the resignation of the employees in these positions, the difficulty of the new employees to start the software will be relatively large.

 Personal advice: In the current development stage of the card, I personally suggest that consumers choose the card (multiple software and multiple databases share a card) mode is more practical and wise. Large units (the number of doors in the thousands of doors, the number of people in the tens of thousands of people more than the system investment is relatively large) can consider the "card + a soft pass + a library pass" model. However, after commissioning, the cycle of investment and use may be relatively long, and the service level of the engineering company should be adequately assessed, so it is best to prepare and consider in advance.
