RFID tags for production processes in the automotive industry

In the automotive industry, the use of RFID tags and RFID reading and writing devices is growing day by day at every step of the production processes, because it is the most reliable way to identify the parts that correspond to each car configured by each customer.

An RFID system can cover every identification need of every plant task from metal plates workshop until the car leaves the factory. The majority of personalizations of a car materialize during assembly, so there are many versions of the same model in the production line. With RFID solutions, the identification of each piece and each car is accurate and updated in real time.

The RFID technology is not only reliable and fast, but it is also very resistant to the roughness of manufacturing, such as high temperatures or corrosive substances. The RFID tags that are used in this sort of industrial implementations are single-use labels which are usually destroyed during or at the end of the manufacturing process.

RFID tags suitable for automotive production processes

On the one hand, there are RFID tags that will work on metal (which interferes with the operation of radio frequency waves), and on the other, those that will be on hard plastics, glass and other materials.

In addition, the materials in which the inlay should be (RFID antenna with a chip inserted on a substrate) must be resistant to the appropriate temperatures and to the substances used in manufacturing.

The RFID tags that work on metal adhere to the piece and are usually on a material that separates the metal antenna from one to two millimetres, so that it does not interfere with the performance of the RFID tag. Another solution to label with RFID metal parts is to use flanges, so that the label is hung and not attached to the sheet, but this solution is not always possible due to issues such as the type of handling of the parts.

As for the RFID tags that are going to adhere to hard plastic parts, these are adhesive RFID tags that do not need that distance between the piece and the antenna.

Small UHF RFID tags OPPD6 sticking on the tagging objects

industrial UHF tags

OPP IOT has recently developed UHF Metal Tag-OPPD6, which is designed to mount on metal for tracking usage. In spite of the metal weakening effect on read range, this kind of metal mount RFID tag combines small footprint and stable detecting performance in metallic environment.

By using this UHF metal mount RFID tag, identification around metal or on metal surface is guaranteed to keep high accuracy. It measures 6mm in dia. And small size as it is, this UHF metal tag behaves well in metal environment. What’s more, the capability of storage could be in 96 bits, 512 bits or 2K bits, making it flexible in inventory management.

With these small UHF RFID tags sticking on the tagging objects, it is quite suitable for tracking goods around metal. Furthermore, this small metal mount RFID tag can support ISO18000-6B or ISO18000-6C (EPC C1 Gen2) standards. And it is engineered to provide a read range from 0.45m to 0.85m basing on a normal UHF Reader, specifically to be integrated to RFID management project in metallic environment.

Everest Series passive UHF RFID tags

Under the first layer– the anodized aluminum nameplate–rests two more layers, a foam layer, and a foil layer. Within the foam layer is a cavity that holds a custom engineered RFID inlay, the heart of the tag. The foam keeps the first and third metallic layers apart to keep them from grounding out the tag.
The thin third and final layer, the foil layer, seals off the back of the tag but is also part of the tag mechanization. Reflecting any signal coming in from a reader, it makes interactions with the tag reader possible. Bonding each layer are specialized adhesives. The three layered stack ends with a bonding agent designed for unparalleled adhesion that attaches the tag to the consumer’s product or asset.

Magnetic Metal RFID Tag OPP9020M


OPP9020M Magnetic RFID Tags are suitable for tagging metal assets as the magnetic force makes attachment easier. Our magnetic metal tags’ antennae are made of a combination of Cu and FR-4 grade epoxy laminate. Due to the properties of FR-4 grade material which include effective electrical insulation, high mechanical strength, and minimal water absorption, our magnetic metal RFID tags are built to last and will endure most industrial situations. Our magnetic metal tags are waterproof and heat-resistant.

Passive RFID Systems

In passive RFID systems the reader and reader antenna send a radio signal to the tag. The RFID tag then uses the transmitted signal to power on, and reflect energy back to the reader.

Passive RFID systems can operate in the low frequency (LF), high frequency (HF) or ultra-high frequency (UHF) radio bands. As passive system ranges are limited by the power of the tag’s backscatter (the radio signal reflected from the tag back to the reader), they are typically less than 10 m. Because passive tags do not require a power source or transmitter, and only require a tag chip and antenna, they are cheaper, smaller, and easier to manufacture than active tags.

Passive tags can be packaged in many different ways, depending on the specific RFID application requirements. For instance, they may be mounted on a substrate, or sandwiched between an adhesive layer and a paper label to create smart RFID labels. Passive tags may also be embedded in a variety of devices or packages to make the tag resistant to extreme temperatures or harsh chemicals.

RFID tag application in Laundry tracking application

Hospitals, hotels, laundry facilities, or any company with multiple types of textiles have a sorting process for laundering purposes. The laundering process is usually facilitated by 2-8 people at different laundry chutes, and employees may spend hours sorting through laundry. Many laundries are turning to UHF-RFID technology to gain better control of their operations and reduce costs. Early installations prove the technology works.

Laundries report the following results from UHF-RFID tracking system use:
1. Fewer losses and lower inventory replacement costs.
2. Total control identifies loss points and enables remedial actions.
3. Improved labor productivity.
4. Fewer customer complaints.
5. Validated deliveries and pick-ups at customer locations.
6. Improved revenue opportunities and long-term customer relations.
7. Tag and track customer-owned goods or rental items.

RFID tag application in Anti-counterfeit protection

RFID tags can protect your products from counterfeiting and return fraud. Brand owners use RFID tags to validate the authenticity of items and can then take action against unauthorized resellers. During manufacturing, a special brand RFID tag or label is added to your products.

1. Enable your sales teams with easy-to-use tools for authenticating items
2. Allow associates and brand scouts to use mobile devices to verify and validate the origin and authenticity of products in the field.
3. Ensure the authenticity of your branded products and protect their value.
4. Monitor your sales channels and goods as they move through markets.
5. Protect your resellers and customers from fraud and criminal activities.
6. Identify grey market goods and the source of those products entering the market.
