Proximity Badges
By default, ATS Supports 26-bit Wiegand™ and 34-bit standard binary data format for
proximity badges and readers, such as those provided by HID.
The 26-bit format is an open format, which means the format description is not proprietary
but is available publicly for any manufacturer to use. The 26-bit format is a widely used
industry standard. The 26-bit format includes:
•
The maximum facility code is 255, which is the decimal equivalent of setting all eight
facility code bits to one.
•
The maximum card number is 65,535, which is the decimal equivalent of setting all
sixteen card number bits to one.
•
A parity bit is used to check the accuracy of transmitted binary data.
Additionally, ATS offers a service that allows a structured data string to be sent to the terminal
to support additional binary data formats up to 75 bits. To use this service, a customer provides
ATS with the decoding format and ATS creates and provides a custom string for use with their
terminal.
Please contact ATS technical support at 860-870-5000 if you need additional assistance.
