\n
\nThe ESP-RFID-Tool is a tool created for logging Wiegand data and also for testing devices that contain a Wiegand Interface. The primary target group is 26-37bit HID Cards but it will also work with most devices that output Wiegand data. ESP-RFID-Tool can be combined with a RFID reader and a battery to create a portable standalone RFID badge logger, it can also be integrated into existing systems without the need for a battery and instead drawing its power directly from the wiring in the existing installation. The ESP-RFID-Tool can read the data from any device that contains a Wiegand Interface and outputs data from 1 bit long up to 4,096 bits long, although anything other than 26-37bit is experimental. The ESP-RFID-Tool is not even limited to RFID technologies, many other devices also contain a Wiegand Interface as it is an access control system standard, this includes pin pads(keypad), magnetic stripe(magstripe), there are even non access control related devices that utilize a Wiegand Interface.

\nAccessing ESP-RFID-Tool Web Interface
\n-----
\n
\nSSID: \"ESP-RFID-Tool\"
\nURL: http://192.168.1.1
\n
\n-----
\nConfigure ESP-RFID-Tool
\n-----
\n
\nDefault credentials to access the configuration page:
\nUsername: \"admin\"
\nPassword: \"rfidtool\"
\n
\nDefault credentials for ftp server:
\nUsername: \"ftp-admin\"
\nPassword: \"rfidtool\"
\n
\nWiFi Configuration:
\n
\nNetwork Type:
\nAccess Point Mode: Create a standalone access point(No Internet Connectivity-Requires Close Proximity)
\nJoin Existing Network: Join an existing network(Possible Internet Connectivity-Could use Device Remotely)
\n
\nHidden: Choose whether or not to use a hidden SSID when creating an access point
\n
\nSSID: SSID of the access point to create or of the network you are choosing to join
\nPassword: Password of the access point which you wish to create or of the network you are choosing to join
\nChannel: Channel of the access point you are creating
\n
\nIP: IP to set for device
\nGateway: Gateway to use, make it the same as ESP-RFID-Tool's IP if an access point or the same as the router if joining a network
\nSubnet: Typically set to 255.255.255.0
\n
\nWeb Interface Administration Settings:
\n
\nUsername: Username to configure/upgrade ESP-RFID-Tool
\nPassword: Password to configure/upgrade ESP-RFID-Tool
\n
\nFTP Server Settings:
\n
\nNote: Supports Passive(PASV) Mode Only!
\nEnabled: Turn FTP Server ON
\nDisabled: Turn FTP Server OFF
\nUsername: Username to login to ftp server
\nPassword: Password to login to ftp server
\n
\nPower LED:
\n
\nEnabled: Turn ON Power LED
\nDisabled: Turn OFF Power LED
\n
\nRFID Capture Log:
\n
\nUseful to change this value to differentiate between facilities during various security assessments.
\nFile Name: File name to save captured RFID tags to for the current security assessment.
\n
\n-----
\nList Exfiltrated Data
\n-----
\n
\nDisplays all log files containing RFID tag captures.
\n
\n-----
\nFormat File System
\n-----
\n
\nThis will erase the contents of the SPIFFS file system including ALL RFID tag captures.
\nFormatting may take up to 90 seconds.
\nAll current settings will be retained unless you reboot your device during this process.
\n
\n-----
\nUpgrade ESP-RFID-Tool Firmware
\n-----
\n
\nAuthenticate using your username and password set in the configuration page.
\n
\nDefault credentials to access the firmware upgrade page:
\nUsername: \"admin\"
\nPassword: \"rfidtool\"
\n
\nSelect \"Browse\" choose the new firmware to be uploaded and then click \"Upgrade\".
\n
\nYou will need to manually reset the device upon the browser alerting you that the upgrade was successful.
