RFID Tag Characteristics
Usage Features of RFID Tags
• RECOMMENDED APPLICATION FIELDS
For dry inlays the recommended applications refer to the suggested uses after conversion in RFID labels, tickets and other finished products.
• RECOMMENDED DIRECT APPLICATION MATERIALS
For dry inlays the recommended applications materials are those suggested after the conversion in finished RFID tags: labels, tickets, badges, special RFID labels or tags. Further notes about suggested integration/conversion materials can be available in the Usage Notes field of the VeryFields Spec Sheets.
Do take into account that presence and proximity of absorbing materials (i.e. liquids contained in a bottle or human body) and detuning materials (metals) can affect read ranges of UHF RFID tags in particular.
• ATTACHMENT METHODS
For dry inlays the Free air option is usually associated to dry inlays which are well suited for conversion in RFID hang tags.
• SUGGESTED BY THE MANUFACTURER FOR USE ON LIQUID CONTAINERS
The value is YES for the RFID tags which are suggested for tracking containers filled with liquids regardless of the container surface material. The value is set to YES if attached to a metallic container for RFID tags well suited for liquid containers and suggested for both metallic and non-metallic surfaces.
• ON-METAL TAG
The value is YES for all the RFID tags which can be fixed to metal surfaces directly, without any kind of spacer or shield.
• NEAR-METAL TAG
YES is for RFID tags which are able to work well in close proximity to metal (few millimeters).
• APPROXIMATE MAXIMUM READ RANGE
The published value is the one declared by the tag manufacturer and can refer to particular measurement conditions. Please consider that read ranges are affected by several conditions such as proximity to absorbing materials (i.e. liquids) and detuning materials (metals), working frequency, application surface material, temperature, type and performance of the used readers.
Usually, for RFID tags suggested for both metal and non-metal applications the published value refers to the maximum read range they can provide when attached to metal.
More details about read ranges of tags can be available in the Usage notes field of the VeryFields Spec Sheets.
• UHF NEAR FIELD CAPABILITY
It is YES for UHF RFID tags which can be read by with UHF near field antenna
• DENSE SMALL TAGS ENVIRONMENT
This parameter is set to YES for ISO 18000-3 Mode 2 tags, and for passive Gen 2 RFID tags smaller than 50×50 mm which are well suited for use in dense tag population applications thanks to their marked near field effect. Dense small tags environment means that tags are stacked or in close proximity (few millimeters) to other tags.
• SMALL ITEM LEVEL OMNI-DIRECTIONAL
It is YES for UHF tags smaller than 50×50 mm which don’t feature a double dipole antenna yet are able to provide good orientation insensitivity thanks to the special design ot their single dipole antenna. Usually, these passive RFID tags are designed for apparel and other item-level applications where orientation of tags can’t be controlled such as apparel tagging.
• LONG RANGE OMNI-DIRECTIONAL
This parameter is YES for active RFID tags, some passive UHF RFID tags (not inlays) which provide 360° read angle thanks to their special design, and UHF RFID inlays featuring double dipole antenna.
This characteristic makes these RFID tags well suited for applications where high orientation insensitivity is needed.
