Card Dispensers in Cashless Vending Machines
Card dispensers are an integral part of cashless vending machines. They dispense magnetic stripe cards, chip cards and contactless cards.
In addition, they can also be used to dispense gift cards. They are an important component of the overall vending system and need to be fully integrated mechanically, electrically and on the software side. 카드단말기대여
Magnetic stripe cards
Magnetic stripe cards, or magstripes, are an extremely simple, yet highly effective, way to store and process personal data. They’re essentially small, plastic stripe stickers that are embedded with a unique code that can be read when swiped through a card reader.
Once the stripe is swiped, a card reader uses a magnetic current to decode the embedded information. The card reader then sends this data to a point-of-sale system for processing, and the system either approves or denies the transaction.
Credit and debit card holders around the world swipe their cards through magstripe readers more than 50 billion times a year. These cards interweave with our daily lives in many ways – from transport systems to access control at hotels.
They’re often used for hotel room keys and other forms of ‘access restriction’, and they can also be used for identification and loyalty cards. However, their use has come with some problems – for example, if the stripe becomes damaged through wear and tear, it may no longer be read by a card reader device.
Chip cards use a microchip to “talk” to card dispensers at merchants. These chips contain all of the cardholder’s information, including their name, account number, and expiration date.
These information is then used to make a purchase. This process works because the microchip produces a unique code each time it is used, which is impossible to duplicate.
When you swipe your card through a chip-enabled reader, it sends that code to the point-of-sale terminal to verify your identity and authorize the transaction. This is a lot more secure than storing your information on a magnetic stripe, which can be copied and used for fraudulent transactions.
The chip technology has made it difficult for fraudsters to copy your data, but it does not address the issues of lost and stolen credit card data. Retailers have had to move on to more sophisticated security measures, like point-to-point encryption and tokenization, to prevent in-store theft of card information.
A contactless card is a credit or debit card that you can use to make payments without putting it into a chip-and-pin reader. You can use it at stores, restaurants and other locations that accept contactless cards.
When you tap a contactless card, it generates a unique cryptographic code that the merchant’s system transmits to the card issuer. The card issuer then checks the information and authenticates the transaction. 카드체크기
If the transaction is approved, the system will send an acknowledgement to you with a beep, green light or checkmark. The card issuer also verifies that the payment is from the correct card and that the amount is within your available balance.
These are popular options for public transportation fare payments and in some cases, they do not require a PIN. However, this can increase the risk of your card being stolen or misused by an attacker who tries to use it fraudulently.
SIM cards are used to connect your phone to a mobile network. This allows you to make and receive calls, send text messages and access mobile internet services.
Each SIM card holds a user’s IMSI (International Mobile Subscriber Identity) and ICCID (Integrated Circuit Card Identifier) information, as well as security authentication and ciphering data. This lets cellular operators know who is using the card and if it has permission to access the network.
They can also contain an advice of charge, a mobile country code, and an authentication key, which helps confirm that the card has been authenticated to a specific network.
A SIM card is also used to store your contact information and other personal settings that you use to manage your phone. If you decide to switch phones, this information can follow the card to your new device!
SIM cards come in three sizes: standard, micro and nano. While standard-sized SIM cards are still used on many phones, most cellular carriers have moved to nano-sized ones.
