NFC (Near Field Communication) is a short-range wireless communication technology that allows two devices to exchange data when brought close together. NFC is used in various applications, including contactless payment, access control, and data transfer.
NFC works by using electromagnetic waves to create a connection between two devices. The devices must be within a few centimeters of each other to communicate. When the devices are in range, they will automatically establish a connection and begin exchanging data.
NFC is a secure technology. The data exchanged between two devices is encrypted, which helps to protect it from unauthorized access. NFC is also a convenient technology. It allows you to quickly and easily share data between two devices without entering any information manually.
Here are some of the ways that NFC is used:
- Contactless payment: NFC is used in contactless payment systems like Apple Pay and Google Pay. When you use a contactless payment system, you tap your phone on the payment terminal to pay for your purchase.
- Access control: NFC is used in access control systems like key cards. You can use an NFC-enabled key card to open doors, gates, and other secure areas.
- Data transfer: NFC can transfer data between two devices, such as photos, videos, and contact information.
- Smart posters: NFC can be used in smart posters to provide additional information about a product or service. When you tap your phone on a smart poster, you will be taken to a website or app that offers more information.
NFC is a versatile technology that can be used in various applications. It is a secure and convenient way to share data and access information.
When you tap your Coqui Card against someone's NFC-enabled device, your contact information is automatically transferred. This makes it easy and convenient to share your information with others, without having to fumble with paper business cards or manually type in your contact information.
Coqui Cards are also more secure than traditional business cards. When you share your contact information with someone using a Coqui Card, your information is encrypted and sent securely over the air. This means that your information is protected from unauthorized access.
Overall, Coqui Cards are a convenient, secure, and modern way to share your contact information with others. If you're looking for a way to make a lasting impression, Coqui Cards are the perfect solution for you.
