What it is
The ShillehTek 13.56MHz RFID Smart Card S50 1K Chip ISO14443A Access Control is a blank white PVC contactless card for ISO14443A systems, designed for read/write credential projects like hotel locks, library cards, cashless vending, and smart-home access control using compatible readers or NFC devices.
Pins
This is a contactless RFID smart card (not a breakout board), so there are no pins or Arduino/Raspberry Pi pinout connections on the card itself. Use an ISO14443A-compatible reader module and refer to that reader’s datasheet/tutorial for wiring and pin labels.

Frequently Asked Questions
Will this 13.56MHz RFID smart card work with NFC on Android or iPhone?
It works with NFC devices that support the ISO14443A standard. Your phone/app must support ISO14443A reading/writing for the specific use case you’re building.
What does S50 1K mean on an ISO14443A access control card?
S50 1K refers to the chip family/capacity and indicates 1K byte EEPROM organized into 16 sectors. This structure is commonly used to store multiple credential data areas with separate sector keys.
Can I write my own data to this RFID card for Arduino or Raspberry Pi projects?
Yes—use an ISO14443A-compatible RFID reader/writer module connected to your Arduino or Raspberry Pi, and write blocks/sectors according to your system’s format. The exact wiring and code depend on the reader module you choose.
How do the per-sector encryption keys help prevent cloning?
Each sector can use programmable keys, so access to read/write protected data can be restricted by your system. Proper key management and access rules make unauthorized copying harder than simple UID-based checks.
Can I print on this blank white PVC RFID smart card?
Yes—the smooth white PVC surface is designed to be printer-ready for thermal card printers, allowing you to create custom IDs, membership cards, or passes.
