Frequently Asked Questions
Q: What is the difference between 125kHz and 13.56MHz RFID modules?
A: 125kHz RFID modules (e.g., EM4100, TK4100, T5577) are commonly used for basic access control and proximity identification. They are generally read-only or rewritable at lower data rates. 13.56MHz modules (e.g., NTAG215, ISO14443A) operate at a higher frequency, support NFC standards, offer faster data transfer, and are compatible with modern smartphones and more advanced smart card applications.
Q: Are the 433MHz wireless remote control modules compatible with Arduino?
A: Yes! Most of our 433MHz RF modules and antennas are fully compatible with Arduino, ESP8266, ESP32, and Raspberry Pi. They use standard ASK/OOK modulation and can be paired with popular libraries like rc-switch to send and receive 433MHz signals in your DIY or prototyping projects.
Q: Can the rewritable RFID key fobs (T5577 / EM4305) overwrite existing cards?
A: Yes. T5577 and EM4305 key fobs are rewritable and can be programmed to emulate most standard 125kHz read-only cards. Using an RFID duplicator or cloner, you can copy an existing EM4100 or TK4100 card's ID onto a blank T5577/EM4305 fob, making them ideal for backup credentials or access control development.
Q: What range can I expect from 433MHz RF remote control modules?
A: The effective range of 433MHz RF modules depends on the antenna, environment, and transmission power. In open-air conditions, standard modules typically achieve 50–100 metres, while pairing them with a high-gain antenna (such as our 12 dBi dipole or helical antennas) can extend the range significantly — up to several hundred metres in ideal line-of-sight conditions.
Q: Do the NTAG215 NFC sticker tags work with smartphones?
A: Yes. NTAG215 NFC adhesive tag stickers operate at 13.56MHz and are fully compatible with NFC-enabled Android and iOS (iPhone 7 and later) smartphones. They can be read and written using free NFC apps and are widely used for automation shortcuts, smart business cards, Amiibo emulation, and more.
