The invention relates to a method for transmitting data between a read/write device (SLG) and a mobile data memory (D, HD) in an identification system for capturing object-related data. Said method comprises the following steps: division of the data transmission between the read/write device and the data memories into several time slots (SLOT), subframes (SUBFRAME) and frames (FRAME); receipt and evaluation of an identification time slot (S-CH) of the respective data memory in at least one evaluation time slot (S0a); identification of the data memory as a mobile high-speed data memory (HD), if the identification time slot is a high-speed identification time slot (S31,0, S0,31) and evaluation of the corresponding data memory identification block (MB2), at least from the following time slot. The advantage of the invention is that an extremely rapid capture of high-speed data memories (HD) can be achieved.

L'invention concerne un procédé de transmission de données entre un appareil de lecture/d'écriture (SLG) et une mémoire de données mobile (D,HD) dans un système d'identification pour saisir des données concernant des objets. Ce procédé comprend les opérations suivantes : répartir la transmission des données entre l'appareil de lecture/d'écriture et les mémoires de données en plusieurs tranches de temps (TRANCHE), sous-trames (SOUS-TRAME) et trames (TRAME), recevoir et analyser une tranche de temps d'identification (S-CH) de la mémoire de données correspondante dans au moins une tranche de temps d'analyse (S0a), identifier la mémoire de données en tant que mémoire mobile de données à grande vitesse (HD), si la tranche d'identification est une tranche d'identification à grande vitesse (S¿31,0?,S¿0,31?), et analyser le bloc indicatif de la mémoire de données correspondante (MB2), au moins à partir de la tranche de temps suivante. Cette invention offre l'avantage de permettre une saisie très rapide de mémoires de données à grande vitesse HD.
