Frequently Asked Questions
Q: What card types does this dual frequency RFID reader module support?
A: The D82R module supports both 125KHz ID cards (such as EM4100 and HID format cards) and 13.56MHz IC cards (such as Mifare Classic and ISO 14443A compliant cards). This dual frequency capability means it can work with a wide range of common access cards used in residential and commercial settings.
Q: What power supply does this RFID reader module require?
A: This module operates on DC 5V, which is a standard voltage level compatible with most access control system power supplies and microcontroller development boards (such as Arduino or Raspberry Pi). No special power converter is needed for typical installations.
Q: Can I use this module as a replacement part for my existing access control system?
A: Yes — the D82R is designed as a spare and replacement reader module for access control systems. Its compact size (5.6 × 3.2 × 1 cm) allows it to fit into most standard enclosures. Always verify pinout and signal compatibility with your specific access control panel before installation.
Q: Is this module suitable for DIY access control projects?
A: Absolutely. Its dual frequency support, standard DC 5V power input, and compact form factor make the D82R an excellent choice for DIY electronic security and smart lock projects. It integrates easily with microcontrollers and access control panels.
