Roxen CSE out of heavy metal tag adapter

Switzerland Roxen CSE recently launched an RFID tag adapter, which is mainly suitable for low-frequency (125MHz-134MHz) passive RFID tags to enhance the RFID tag's ability to receive information under the influence of heavy metals. William Gillispie, Roxen's manager, said: "This technology is suitable for standard read-write equipment for a variety of business processes. It meets the requirements of low-frequency RFID tags and can increase the read rate of tags in metal environments."

Everyone knows that metal will interfere with the RF signal, because the signal will generally appear after metal reflection, affecting the reading effect. In order to solve the problem of metal interference to the signal, many companies have switched to active RFID tags that can transmit strong RF signals. The new solution introduced by Roxen CSE adds a miniature adapter that improves signal transmission and reception efficiency.

Roxen did not disclose information about the working principle of the adapter, production materials, and price of the product. Although this adapter uses the products of many European suppliers, these companies did not participate in the design process. Instead of selling adapters separately, Roxen uses the first to purchase the tags, and then sells the adapters in an integrated manner on the tags, which are generally sold to medical institutions, industrial users, and others. Gillispie said: "We start with the promotion of the medical market, which is determined by the needs of the market."

Roxen's original intention of designing passive tag adapters was to avoid the use of active tags as much as possible - this cost is relatively high. The initial design idea was to consider from the medical institutions. By adopting this kind of "tag + adapter" products, medical institutions can reduce the configuration of RFID. The cost of the system. In addition, users who have adopted low-frequency (LF) passive RFID tags can directly use Roxen's extension technology and can also use this adapter.

Roxen conducted performance tests on adapters mounted on low-frequency RFID tags at companies such as Texas Instruments, Sokymat, and EM Microelectronic. Gillispie said: "Some low-frequency tags have not worked well under the condition of an adapter. We have encountered it, but it is quite rare. But in general, the tag work is still relatively normal. We can meet different requirements of users. The corresponding adapter is designed; the adapter is more flexible and can be placed outside the label or inside the label.”

This adapter can only be used in the 125MHz-134MHz frequency band, and is mainly designed for the metal environment, especially designed for the impact of steel. Since the price of the adapter depends on the type of tag the user uses, different types of adapters also have different prices. Roxen's goal is to reduce its price to about 40% of active tags.
