1: Anti collision is a technic to select and use a transponder when there are a few transponder with in the antenna field.
2: Memory capacity without regions that are not usable for data like password and checksums.
3: The distance is highly dependent on the packaging of the transponder (disk, card etc.) and the reader used. Our typical distance is based on practical experience with our readers. Other manufactures mostly state the theoretical maximum distance which usually is not achievable.
