These are in quantities of 10, 25, 50 and 100 and in Green, Amber or Red tokens. Packs can be ordered in any combination and any quantity (up to the maximum number of users, 10,000). Each pack contains user tokens with their associated shadow cards.
The Switch2 tokens have a read range of 0.85 to 2.5 meters, with up to 5 meters when using the long range reader. Card packs are registered to a system by presenting them to the reader, and then when given to the user the name of the user is written down on the corresponding shadow card, so when you want to restrict access to a certain user you simply present the shadow card to the reader to invalidate it.
