A common method of automatic identification is the barcode.
Barcode labels are inexpensive to purchase and therefore ideally suited at first glance.
Unfortunately, the barcode often has cost-driving disadvantages in daily use.
Reading barcodes requires direct visual contact, since a barcode is read with the help of a scanner. Contamination or unevenness of the sticker may result in misreading.
Therefore, it must be reworked manually, which leads to further sources of error in the process and relativizes the cost advantage of the barcode. Solutions for this offer the (Radio Frequency Identification) technology also called RFID. This name stands for a subgroup in identification technology and means: Identification by means of radio frequency, contactless. An RFID system includes an RFID data carrier, also called "transponder" or "TAG", and an RFID identification system that consists of an electronics unit and an antenna.
Often these electronics are misleadingly referred to as "readers" (readers), because transponders can be described with the help of these systems with information. That's why the name "read-write system" is more appropriate. Transponder is an artificial word and can be derived from "Transmit" and "Respond", or sending and receiving. Transponders can be used in various designs, such as glass tubes, check cards or flexible labels. Information can thus be written with an RFID read-write system in a transponder and read out of a transponder. This is done contactless over an air gap by means of a field between the transponder and the antenna of the RFID read-write system.
RFID technology is increasingly finding application in medicine for the identification and identification of medical instruments, medical laser probes and other consumables.
The use of this technology enables a safe and optimized sequence of the process for the patient and the user in comparison to conventional identification technologies such as the barcode in various medical fields.
The speed of identification is increased, paper-based processes are eliminated and thus integrated, media-free business processes are made possible.
