R20C USB HF MIFARE Card Reader – 13.56 MHz
The R20C USB HF MIFARE Card Reader is a compact desktop RFID reader designed to transfer the identification number of compatible 13.56 MHz contactless cards directly to a computer. Through its USB connection, the reader can be installed quickly and can automatically enter the card identification number into the active software field when a compatible card is presented.
The R20C can be used in personnel attendance systems, visitor registration applications, membership platforms, access-control software, parking management and user-identification projects. In keyboard-emulation configurations, the card number can be entered directly into Notepad, Excel, web applications, registration forms or compatible enterprise software.

Important Card Compatibility Information
The R20C does not automatically support every 13.56 MHz contactless card. The protocol, chip type, UID structure and data format expected by the software should be checked before product selection. Projects requiring card-memory writing, encrypted-sector access or secure authentication may require a different reader instead of a standard UID reader.

Frequently Asked Questions
Which cards can the R20C read?
The R20C can read the identification number of selected 13.56 MHz cards, including MIFARE S50, S70, NTAG203 and compatible ISO 14443A cards. The card chip model should be confirmed before use.
Does the R20C require a driver or special software?
Configurations operating as a standard USB keyboard-emulation device generally do not require an additional driver. Special output formats or custom software integration may require configuration or additional software.
Which applications can receive the card number?
The card number can be entered into the active field in Notepad, Excel, web forms, attendance software, membership systems or other compatible text-entry applications.
Can the R20C write data to a card?
This product is primarily intended for reading card identification numbers. Projects requiring data writing or access to encrypted card sectors may require a different reader configuration or model.
Can the R20C be used with attendance and access-control software?
Yes, provided that the software accepts a card number entered through keyboard input. The required card-number length and data format should be compared with the reader output before deployment.
