This allows the transformation of a long-range tag into a proximity tag that still may be read, but only at short range — less than a few inches or centimeters. When first introduced, the encryption on the new U. The shear strength test principle is based on the solder ball shear test standard , as shown in Fig. Collision detection is important to allow reading of data. The control is enabled to automatically start subsequent process steps. The scanners used to read these devices can also provide enough electricity to allow them to read the microchip.

This may help companies cope with quality deficiencies and resulting recall campaigns, but also contributes to concern about tracking and profiling of consumers after the sale. However, read range is a function of both the reader and the tag itself. These standards include conformance, performance and interoperability tests. Teknologien styres ved hjælp af radiobølger, der kommunikerer mellem en og. Disse løsninger bruges hvis der ønskes transparens ifht. In this region, the tag is closely coupled electrically with the transmitter in the reader. Two-way radio transmitter-receivers called interrogators or readers send a signal to the tag and read its response.

The return signal of the tag may still cause for other radio users. Rush error, lap count errors and accidents at start time are avoided since anyone can start and finish any time without being in a batch mode. Ski jackets have a left pocket into which the chip+card fits. International Journal of Medical Informatics. Archived from on 28 February 2006. However, as of 2008 this technology remained too costly for many smaller libraries, and the conversion period has been estimated at 11 months for an average-size library.
