The RFID application consists of RFID printers and readers, RFID tags and an information system.

An RFID printer and reader are devices that allow the content of a tag to be written and read without contact or even visual contact with the object. The reading distances depend on the frequency, the power used, the sensitivity of the reader and the direction pattern of the antenna.

An RFID tag is a sticker, card, tag, button, implant, etc. attached to an identifiable object that includes an antenna and a small microcircuit.

EPC = Electronic Product Code

The EPC standard identifiers have a unique serial number in addition to the information contained in the traditional barcode. EPC is the GS1 standard for RFID. EPC increases supply chain efficiency and visibility by enabling the identification and tracing of individual items.

When using the GS1 System, unique identification in EPC solutions is also based on GS1 identification keys generated on the basis of the GS1 Company prefix. In accordance with the EPC principle, each identifier is completely unique, which is why for the EPC format, some of the keys must be specified by serial numbering

  • GTIN -> SGTIN - Serialized Global Trade Item Number 
  • GLN -> SGLN - Serialized Global Location Number 
  • SSCC - Serial Shipping Container Code 
  • GRAI - Global Returnable Asset Identifier 
  • GIAI - Global Individual Asset Identifier 
  • GSRN - Global Service Relation Number
  • GDTI - Global Document Type Identifier 
  • You can change the data content you want to the format you put on the RFID tag using a free generator EPC Converterter


EPCIS = Electronic Product Code Information Services

For example, location-specific identification information collected by an information system can be used to monitor the movement of goods in the value chain and streamline operations.
