Data acquisition using an RFID tag

RFID tags enable efficient tracking and management of your assets - in addition to real-time insights into locations, RFID technology also provides information about the movement and condition of your items. With our RFID tags and RFID gates, you can optimize your processes and increase accuracy.

 

How does data collection work?

Data collection using RFID tags, small devices containing a chip and an antenna, is achieved by attaching a tag to an object or container. The RFID tag contains a unique identifier and can store additional information such as the contents or object properties of the item.

RFID readers equipped with RFID antennas are used for data collection. These transmit radio waves and receive the responses from the RFID tags. The information from the RFID tag is recorded by the reader and transmitted to GRAIDWARE, an RFID middleware from SIGMA. There the data is processed and stored in a database.

This data collection allows you to track and manage the location, movement and status of RFID-tagged items in real time.

What data can be stored on an RFID tag?

[Translate to English:] RFID Tag

Various data can be stored on an RFID tag, depending on the requirements and the intended use. As a rule, a unique identifier (ID) is stored on the RFID tag, which is used to identify the container or object. In addition, user-defined data such as the contents of the container, the order, the status, the location and historical data that provide information about the life cycle or other relevant information can be stored in the user memory.

How much memory does an RFID tag have?

The size of this memory area and the restrictions on the data that can be written to it vary depending on the RFID chip used in the transponder. However, RFID tags can provide further information when scanned using web addresses and links, which would exceed the capacity on the chip.

The stored information can then be stored and managed in a database or ERP system.

Guide to implementing an RFID tag

As an experienced RFID system integrator, we support you with all these questions and tasks from the very beginning right through to the commissioning and live operation of the RFID solutions we implement.

 

  1. Understanding the use case: Before implementing an RFID tag, it is important to understand the use case. What type of information should be tracked or monitored? Which processes are to be optimized through the use of RFID?
  2. Select RFID technology: There are different types of RFID technologies, including passive and active RFID tags as well as different frequency ranges. Choose the RFID technology that best suits your requirements. Consider range, read speed, cost and environmental factors.
  3. Selecting the RFID tag: Decide on the right RFID tag based on your requirements in terms of size, shape, read range and storage capacity. Ensure that the selected tag can store the required information or make decisions about which data should be stored in databases instead.
  4. Hardware selection: Select the appropriate RFID hardware, including readers and antennas, that is compatible with the RFID tags and meets the requirements of your use case. 
  5. Integration with existing systems: Plan the integration of the RFID system into your existing infrastructure. Make sure that the RFID readers can communicate with your databases, ERP systems or other relevant systems.
  6. Test and validate: Before you fully implement the RFID system, perform extensive testing to ensure that it works properly and meets requirements. Validate the accuracy of the data and the performance of the system.
  7. Scalability and maintenance: Plan for the scalability of the RFID system to support future requirements and expansions. Set up regular maintenance and review processes to ensure that the system is working optimally.
  8. Continuous improvement: Monitor the performance of the RFID system and collect feedback from users to make continuous improvements and maximize the efficiency and effectiveness of the system.

RFID: Advantages over other data capture technologies

[Translate to English:] Icon Barcode
Barcode scanner

Compared to barcode scanners, RFID enables contactless data capture and offers greater efficiency and accuracy when identifying objects or people. While barcode scanners require a direct line of sight between the scanner and the barcode, RFID tags can be read from a distance, making it easier to capture data in challenging environments.

 

[Translate to English:] NFC
NFC

NFC is a wireless technology that works in a similar way to RFID, but over shorter distances. NFC enables wireless communication between NFC-enabled devices, such as smartphones or NFC tags. NFC can be used for identification and data capture in various applications, but requires closer proximity between reader and tag compared to RFID.

 

[Translate to English:] QR-Code
QR codes

QR codes are two-dimensional barcodes that can be read with a QR code scanner from mobile devices or special scanners and can contain information such as text, URLs or other data. Compared to QR codes, RFID offers faster and automated data capture without manual intervention.

 

[Translate to English:] Biometrische Identifikation
Biometric identification

Biometric identification technologies use physical or behavioral characteristics of a person, such as fingerprints, facial recognition or iris scanning, to verify identities and capture data. These technologies offer high security and accuracy, but require specialized hardware and can be more costly. RFID also allows for greater flexibility and scalability in terms of the number of objects or people to be identified.

 

[Translate to English:] Bluetooth Low Energy
Bluetooth Low Energy (BLE)

BLE is a wireless communication technology that works similarly to RFID, but is based on Bluetooth technology. BLE tags can be used to identify and locate objects or people and provide wireless communication with Bluetooth-enabled devices such as smartphones or gateways. While BLE tags require batteries that require appropriate maintenance management, RFID transponders are passive devices that do not have their own power source. This is one of the reasons for the low cost of RFID transponders.
