SAFR does not support QR codes but does support a similar code called April Tags. April tags are patterns that represent unique integer values.
SAFR enables robust package-counting/tracking and staff-tracking systems, with detection at 20 pixels, at any rotation or angle. Supports billions of unique codes.
SAFR supports badges that are much like QR codes but specially designed for visual detection at extreme angles and any orientation. One such standard is known as April Tags. Each April Tag represents a unique code. A single April tag represents one of 512 unique values but combinations of April tags can be used to represent millions of unique values.
