What are the types of membership cards? The following is the introduction of Shenzhen card manufacturers:
· Magnetic card
A magnetic card is a card that uses magnetic carriers to record information and is used for identification or other purposes. According to the different substrates, magnetic cards can be divided into PET cards, PVC cards and paper cards; depending on the structure of the magnetic layer, it can be divided into magnetic stripe cards and fully coated magnetic cards. Magnetic cards are easy to use, cheap to manufacture, and extremely versatile. They can be used to make credit cards, bank cards, subway cards, bus cards, ticket cards, phone cards; electronic game cards, tickets, air tickets and various toll cards. Today, we use magnetic cards on many occasions, such as dining in the cafeteria, shopping in the mall, taking buses, making phone calls, entering restricted areas, and so on.
Recharge card A kind of one-time, non-reusable PVC card or paper card with a certain denomination and price. It is used to recharge a specific stored-value card or a certain service, such as various game recharge cards and game point cards.
· IC card
IC card refers to integrated circuit card. Generally, the common IC card uses radio frequency technology to communicate with the IC card reader. There is a difference between an IC card and a magnetic card. An IC card stores information by an integrated circuit in the card, and a magnetic card records information by magnetic force in the card. IC cards are generally more expensive than magnetic cards, but have better security. < /p>
Answer: Different types of cards have different data reading and writing devices according to their working principles and identification technology. There are--
Magnetic card-magnetic card reader, magnetic card reader, bar code card-bar code printer, infrared bar code reader (CCD), laser bar code reader RF ID card-RF ID / EM card reader contact IC card-contact IC card reader (MEMROY card, CPU card)
Non-contact IC card-RF IC card reader (different frequency band or compatible multi-frequency band)
Electronic tags (cards)-electronic tag antenna receiving devices, tag readers, middleware. In addition, printers-most currently use thermal models and thermal transfer models as mainstream printout devices. Current card reader device manufacturers. There are many agents and many brands. Due to the adoption of internationally unified technical standards, domestic manufacturers' products are not essentially different in function from imported products, and their prices are more than half cheaper. The main concern of users is the failure rate, service life, after-sales maintenance service period of these devices, and whether the supplier provides free machine backup services.
In addition, from a technical perspective, the card read and write equipment and computer interface methods (COM port, keyboard port, USB port, all-in-one, etc.) and power supply methods (external power supply, COM port, USB port, keyboard port, etc.) also Very important.
Answer: Non-contact IC card, also known as "contactless IC card" or "radio frequency card", is a new technology developed in the world in recent years. Its chip is completely enclosed in the card base, and there is no exposed part. Not only that, there is also a micro antenna embedded in the card body, which is for the mutual communication between the embedded chip and the card reader. It uses radio wave or electromagnetic field induction To exchange information. It successfully combines radio frequency identification technology and IC technology, solves the two major problems of passive (no power in the card) and contact-free, which is a major breakthrough in the field of electronic devices.
The advantage of this technology is that the exchange of information does not require any contact between the card and the reader. The storage capacity of this kind of card is generally between 256b and 72kb. Currently the most popular technologies are Legic, Mifare, Desfire, iCode and HID iclass. At the same time, it also complies with ISO14443 A & B communication protocol chip. It is usually used in places such as access control, bus toll, subway toll, etc.
The metal contacts of the chip of the contact IC card are exposed, and it can be seen directly that the data is stored in the integrated circuit (IC) embedded in the card body, and the 8 contacts on the chip can contact and exchange information with the reading and writing device. Most of the currently used IC cards belong to this category. According to the storage medium, the two most commonly used contact card types are memory cards (MEMORY cards) and processor cards (CPU cards). The memory card can only store 256b to 128kb of data, while the processor card is storing data
The non-contact IC card and the reader complete the reading and writing operation by radio waves. The communication frequency between the two is 13.56MHZ. The non-contact IC card itself is a passive card. When the reader reads and writes to the card, the signal sent by the reader is composed of two parts: one is the power signal. After the signal is received by the card, it is L / C generates a momentary energy to supply the chip with work. The other part is the instruction and data signal, which instructs the chip to complete the data reading, modification, storage, etc., and returns the signal to the reader to complete a read and write operation. The reader is generally composed of a single-chip microcomputer, a dedicated intelligent module and an antenna, and is equipped with a communication interface with a PC, a printing port, an I / O port, etc., so as to be applied in different fields.
Answer: Can I use a transportation card for train tickets? Gently swipe to save time and effort, saving time waiting in line. Yesterday was the first day of the opening of the "People's Mailbox" in this ??天天电玩城??paper. Enthusiastic citizens eagerly wrote to tell the public opinion. One of the readers named "Zhou Xiongming" sent three emails in one breath. This suggestion was particularly cited during the Spring Festival. People concern. To this end, the ??天天电玩城??paper invited Liu Lianqing, a deputy to the Municipal People's Congress and party secretary of the Shanghai Railway Bureau. He said that it is not possible under the current circumstances, but when the time is ripe, a pilot project may be conducted on the future Shanghai-Nanjing intercity railway. It is best to use a transportation card when buying train tickets and long-distance bus tickets to realize the true 'One Card'. Zhou Xiongming said that this is undoubtedly a great convenience for the citizens. The reporter consulted several citizens on this, and most of them agreed. Many people share the feeling that the queue time for buying train tickets is too long now. Part of this is spent at the window to pay the bill. Not only that, but citizens have pointed out that carrying a large amount of cash to buy train tickets has a certain risk factor, and the current transportation card recharge limit is up to 1,000 yuan, and is convenient to keep.
Answer: 1. It can be divided into:
1. Financial card: Also called bank card, it can be divided into credit card and cash card. When the former is used for consumer payment, the funds can be overdrawn at a preset amount; the latter can be used as an electronic wallet or an electronic passbook, but cannot be overdrawn.
2. Non-financial card: Also known as non-bank card, it covers a very wide range and actually covers all areas except financial cards, such as telecommunications, tourism, education, and public transportation.
3 Transportation Cards: Widely Used
4 Government application cards: Nowadays, they are widely used, such as social security cards that have been vigorously promoted recently. Smart card (Smart card or IC Card), also known as smart card, smart card, integrated circuit card and IC card, refers to a portable card plastic that is pasted or embedded with integrated circuit chips. The card contains a microprocessor, I / O interface, and memory, and provides data calculation, access control, and storage functions. The size and contact definition of the card are currently unified by the ISO specifications, and the main specifications are in ISO7810. Common are telephone IC cards, identity IC cards, and some transportation tickets and memory cards.
2. Divided according to the embedded chip:
1. Memory card: The chip inside the card is an electrically erasable programmable read-only memory EEPROM (Electrically Erasable Programmable Read-on
Answer: The surface of the LCD screen looks like a solid black screen. In fact, manufacturers will add a special coating on this screen. The main function of this special coating is to prevent users from being reflected and dazzled by other light sources, and to enhance the color contrast effect of the LCD screen itself. When cleaning, do not wipe the screen surface with any alkaline or chemical solution.
Do not use a general soft cloth or paper towel to wipe the LCD screen. For a soft LCD screen, their surface is still too rough, which easily scratches the delicate LCD screen. Do not use clean water directly. When cleaning, liquids can easily drip into the LCD TV, which will short circuit the equipment and burn out expensive electronic equipment.
If the screen is accidentally stained with juice, coffee and other difficult-to-clean stains, it is recommended to spray a suitable amount of deionized water with a special LCD wiper to make the wiper slightly moist, and then wipe it to make the stains disappear. It will not scratch your LCD screen, but you cannot wipe the LCD TV screen every day to avoid damage to the LCD screen. It is recommended to cover the dust when not in use.
