Operating at the standard 13.56 MHz frequency, it provides reliable communication with NFC tags and cards. This frequency is widely used in the industry, ensuring compatibility with a vast array of existing NFC-enabled items. Whether it’s reading MIFARE cards or interacting with ISO 14443 Type A and B cards, the ACR122U does it with ease.
It supports various smart card interfaces, including ISO14443 Type A & B, MIFARE, and FeliCa. This means you can use it for a wide range of applications, from access control in offices to payment systems in retail. The built-in antenna allows for contactless tag access, with a reading distance of up to 50 mm, depending on the tag type.
The USB Full Speed interface ensures quick and easy connection to your computer or other devices. It’s plug-and-play, making it convenient for both personal and professional use. Whether you’re setting up an e-payment system or verifying personal identities, the USB connection simplifies the process.
With its bilt-in anti-collision feature, only one tag is accessed at a time, preventing data errors and ensuring accurate readings. This is especially useful in environments where multiple NFC tags may be present, such as in a crowded event venue or a busy office building.
The user-controllable bi-color LED and buzzer provide visual and audible feedback, enhancing the user experience. For example, the LED can indicate successful tag reads, while the buzzer can alert users of errors or completed transactions.
- Secure Access Control: Ideal for offices, hotels, and secure facilities, it allows for easy and secure access management.
- E-Payment Systems: Facilitate online micro-payment transactions and electronic payment systems, making it convenient for customers and merchants alike.
- Event and Transit Ticketing: Used for e-ticketing in events and mass transit, reducing the need for physical tickets and speeding up entry processes.
- Network Authentication: Enhance the security of your network by using NFC for authentication, ensuring only authorized users can access.
