In the Hungarian biological laboratories as well as biobanks the used method for the

registration of samples is usual sticky- or barcode labels. In the first case a tipical source

of the fault could be if the assisstant misread or mistype the ID. Although the barcode

technology is a well developed, mainstream technology in the medical biology, use of

this method has got many compromises. First of all, in the case of a succesful

identification barcode label and laser reader needs to be in front of each other. Second

issue is when we want to take a sample out of the freezer and the barcode can not be

read due to the ice layer appeared on the label.

In my thesis, I dealed with a kind of element of an intelligent sample management,

which tries to break the limits of the barcode technology mentioned above. In this

theoretical system, the identification of samples have been done with RFID TAGs

placed on a flexible sticky carrier, which are placed to the tubes of the samples.

In my thesis, I indroduce the historical backgrounds, theoretical basics of the RFID

technology. I examined the effectiveness of modern transponders (TAGs). Due to my

measurements I succeeded to find a type of them which could be appropriate for

medical biology uses, too. I have done some measurements with a test enviroment

based on development proposals. With some references, I planned and built an RFID

reader what could be a proper base of the new registration system.
