UHF-RFID Printing and Encoding with Microplex

Maximum reliability for error-free production of UHF RFID-labels

Passive UHF-RFID tags are used when it comes to making internal processes safe and fast. This includes the automatic determination of inventories or the location of means of production.

UHF-RFID labels are also used for cross-company tracking of products along the entire supply chain. The use of radio frequency identification (RFID) contributes to increasing process effectiveness and efficiency, for example within the automotive industry. This applies in particular to the use of passive UHF (Ultra High Frequency) transponders.

Typical applications are the control and tracking of vehicles, components and (reusable) containers. RFID has been used successfully in the automotive industry for many years, primarily in internal, closed cycles, but also in cross-company, open cycles.

Maximum Reliability for Error-free Production Of UHF RFID-Labels

In the wholesale trade passive UHF RFID tags are being used more and more to optimize the warehousing and logistics process. Passive UHF RFID tags have the advantage that they do not require a battery and are therefore very durable.The labels can be easily attached to products and packaging and enable automated collection of information throughout the supply chain process. This means that the labels can be scanned without manual intervention by employees, which speeds up processes and reduces the error rate.

Setting up the Microplex printer on the respective RFID labels is very easy. Depending on the antenna, the antenna positions (depending on the model) are automatically measured. This ensures optimal performance at all times. Faulty or illegible RFID labels cause disruptions, delays and avoidable costs in the chain of use. Therefore, Microplex printers ensure a printout with 100% readable RFID labels.

Printing process of RFID labels: work steps and verifications.

Printing an RFID label involves three steps. After the print data and the data for programming the RFID chip have been loaded into the printer, the printer first checks the correct function of the RFID chip. To do this, the desired content is written to the chip and then read back and compared with the desired content. Only if both match, the visible part of the label is printed.

If the read/write process fails several times, an invalidation is printed on the label. After that, a successful write is attempted with the next label. How often this happens is also configurable. If a successful write is not possible, the printer stops and issues an RFID error message.
