RTC1000 Proximity Cards for Icon RTC1000-C & SB100-Pro Time Clocks
Selecting the correct proximity card is essential when supporting older Icon time clock systems. These RTC1000 proximity cards are manufactured specifically for use with the Icon RTC1000-C and SB100-Pro proximity badge time clocks. They are designed for the original C-series proximity readers and will not function properly with newer Icon models or other RFID and proximity standards.
Many payroll issues with legacy badge systems come from using the wrong card type. These cards match the original specifications required by early Icon readers, helping ensure consistent badge reads, reliable employee punches, and accurate time records.
Why compatibility matters
Legacy Icon proximity readers rely on a specific card thickness, antenna layout, and chip configuration. Cards designed for newer systems may look similar but will not scan correctly. Using incompatible badges can lead to missed punches, frustrated employees, and payroll errors.
Key card features
- Compatible only with Icon RTC1000-C and SB100-Pro systems

If you are unsure which Icon model you have, check the clock label or serial number. Systems that use these cards typically have serial numbers beginning with the letter “C”.
