A label includes a first portion that is printable with optically readable information and a detachable second portion that has an RFID tag that can be encoded with corresponding RFID information. The printable portion and the RFID portion can thus be printed and encoded, respectively, with information for the same container or object. Both portions can then be kept together until the label is ready to be applied. This greatly reduces the chances of applying mismatched optical and RFID labels.
