What it is
The ShillehTek 125kHz RFID Proximity Smart Card EM4100 For Access Control System is a low-frequency proximity card for instant, contactless entry with most EM4100-compatible readers—useful for offices, apartments, parking gates, attendance systems, and DIY electronic locks.
Pins
This is a passive RFID proximity smart card (not an Arduino/Raspberry Pi module), so it has no pins or wiring. Present it to a compatible 125kHz EM4100 reader; any reader-side wiring/pinout should be taken from your reader’s datasheet and listing photos.

Frequently Asked Questions
Will this 125kHz EM4100 RFID proximity card work with my access control reader?
It is designed for low-frequency 125kHz systems using EM4100 compatibility. Check your reader/controller documentation to confirm it supports EM4100 (or 125kHz proximity) before ordering.
Can I use this RFID card with Arduino or Raspberry Pi projects?
Yes—when paired with a compatible 125kHz EM4100 reader module connected to your Arduino or Raspberry Pi. The card itself has no pins; your wiring and code depend on the reader module’s pinout and datasheet.
Is the ShillehTek EM4100 card waterproof and durable for daily badge use?
The card is made from durable PVC and is described as waterproof and flexible, making it well-suited for daily access badge and attendance use.
Can I print on the card or apply an ID sticker?
Yes. It has a clean white surface intended for printing or adding ID stickers for employee badges and labeling.
