Product Description

T557  RFID Re-writtable UID Card

RFID (Radio-Frequency Identification) technology is widely used for various applications, including access control, inventory management, asset tracking, and more. When discussing RFID cards, it's important to understand the frequency at which they operate and whether they are rewritable.

125kHz RFID: This refers to the frequency at which the RFID system operates. 125kHz is a common frequency for low-frequency (LF) RFID systems. These systems typically have a shorter read range compared to higher-frequency RFID systems but are known for their reliability in close-proximity applications.

Rewritable RFID Cards: RFID cards can be categorized into two main types: read-only and rewritable. Rewritable RFID cards, also known as RFID programmable cards, allow users to write and rewrite data to the card's memory. This is typically done using an RFID writer/encoder, which communicates with the card to update its data.

Here are some key points about rewritable RFID cards:

Memory Capacity: The card's memory capacity determines how much data can be written and stored on it.

Data Types: You can write various types of data to rewritable RFID cards, such as identification numbers, access permissions, or other custom information.

Security: Depending on the specific card and system, there may be security features in place to prevent unauthorized writes or tampering.

Applications: Rewritable RFID cards are commonly used in access control systems, where user credentials (e.g., employee badges) need to be updated or modified regularly. They are also used in applications like public transportation cards, library cards, and more.

When using rewritable 125kHz RFID cards, you'll need compatible hardware, such as an RFID writer/encoder, and appropriate software to manage the card data. Additionally, it's important to consider security measures to protect the data on the cards and ensure that only authorized individuals can make changes.
