Chip card is a payment card with a microchip attached. The computing power of the chip means that smart cards can offer new services, payment options, enhance security, convenience and bring more options.

Chip cards, also known as smart cards (smart cards) usually have quite large memory capacity, usually using its amount is from 64K – 128K.

In addition, the application of the chip card is also used with the function of managing and controlling personnel instead of fingerprint timekeeping to help the personnel management process be automated and more compact. With the store when making loyalty card or vip card can help the process of data synchronization and data management automatically thanks to the software on the computer.

EMV is a global, interactive, secure payment standard. The key factor of EMV is the flexible digital data in every transaction. This makes chip transactions extremely secure and reduces the risk of fraud.

When consumers use an EMV-enabled device to pay at a terminal chip, the transaction is dynamically authenticated, verified and then licensed. Card holders can use a PIN (Personal Identification Number) or sign it as they currently do to verify that consumers are actually holding their device.

Basic and common applications of smart cards include credit cards (ATM cards), fuel cards, SIM cards for mobile phones, TV cards for paid channels, cards for toll collection automatic. Smart cards can also be used as payment wallets at parking lots and vending machines.

In the field of computer security, the hard disk data encryption system (FreeOTFE software) can use smart cards to keep the security keys locked, creating an extra layer for encrypting important data. on disk. The Mozilla Firefox web browser also uses a smart card to store user credentials for the safest browsing. Smart cards are also used to authenticate and allow access to computers without having to use an additional means such as a password.

There are two basic types of chip cards: contactless chip and contactless chip card

Contact chip card:

The type of chip card that you want to write, delete or access the data on the card must have physical contact between the card and the card reader ie the card must be placed in the card slot on the card reader. The advantage of this type of card is better security than contactless chip but slow operation. So for applications that need fast data processing such as timekeeping, parking cards, transportation fees … then we need to use contactless chip cards.

Contactless chip cards:

A type of chip card with an antenna running around the card body allowing the chip to communicate with the card reader within the card reading range (about 2cm to 10cm) instead of having to load into the card reader device.

Thanks to the contactless feature, the contactless card is used for fast and convenient convenience. The processing speed of contactless cards is higher than contact cards. Therefore, contactless cards are often applied in places that need to be processed as quickly as transit systems, on public transport, smart parking machines ..
