More and more people are pouring into the RFID industry. For consumers, this is of course a good phenomenon, because there are more choices, but at the same time there will be some quality problems, and the products are mixed. There will be some differences in quality and quality. This small series summarizes some tips for selecting RFID UHF electronic tags, hoping to help consumers choose and obtain high quality products.
1. Select the type of tag that matches the printer (encoder). The type of label you choose must match your printer (encoder) and application environment, which is the key to the successful application of RFID UHF RFID tags. The rate of data transfer, memory, antenna design, and tag writing capabilities need to be evaluated to ensure that the tag is working properly. Some label vendors may also have different specifications or add some patent-related or non-application-related features. In this case, the supplier should be asked to recommend the UHF electronic label that best suits their application.
2. Perform small batch testing before ordering RFID UHF electronic tags in large quantities. Before ordering a custom UHF electronic tag, you must obtain the requirements for the location of the transponder (ie RFID tag) from your printer (encoder) manufacturer. In the sample test or small batch test phase, these tags must be able to fully meet your application needs before deciding whether to order in large quantities.
3. The storage temperature of the RFID tag should be appropriate. The storage temperature should be between -60 and 203 degrees Fahrenheit (15.5 to 95 degrees Celsius), and the environmental conditions should be stable. Do not expose the label to static electricity, as it will affect the performance of the label. When using RFID UHF electronic tags in low humidity environments, it is best to use antistatic cloth or antistatic mats to eliminate static effects.
4. Train employees to make label printing successful. Label printers (encoders) have a number of parameter settings for your environment, with their own characteristics and special RFID technology requirements, and employees must be fully trained beforehand to avoid possible errors in RFID label printing.
5. Correct the label printer (encoder) to ensure correct printing. Adjust the printer (encoder) before the label starts printing to ensure that the label tape has the correct guide gap and pitch (distance between the two labels) in the printer (encoder). For each new batch of label tapes, it must be adjusted once before printing begins. If it is a special printer for a certain label, the parameters and gaps have been set, and this correction operation can be eliminated. Some label printers (encoders) have an automatic correction function, and the correction operation is simpler.
6. Avoid using labels on metal foil substrates because metal foils reflect radio wave signals and can interfere with RFID. Labels with foil or metal-containing ink can seriously affect accurate printing (encoding) and can seriously affect reading distance.
7. Pay attention to the moisture on the surface of the label. Water vapor or other liquids can be an obstacle to RFID performance because liquids can absorb radio signals, limiting read distance or making label reading and writing difficult. The label's adhesive is also a liquid, and some adhesives or label materials absorb moisture and can also affect the performance of the label.
8. Properly isolate RFID devices. Radio equipment can interfere with each other if they are too close, and the label printer should be kept at a sufficient distance from other products in the same band, such as antennas, readers, wireless LANS or other label printers.
9. Using printer management software, find frequent failures. The ideal state is that the printer can complete the label printing task at one time, but it often happens that the first print is unsuccessful. If this happens frequently, the printer may be defective. Install printers and printer servo management software in your entire RFID architecture to warn you of minor problems, which can avoid serious consequences.
