Seritag stock and sell a limited number of NFC tags. There are four reasons we do this.
If you are new to NFC tags, then even our limited selection can seem a bit confusing. We understand this and you can always contact us for reliable and friendly advice.
As a guideline to get you started let's break things down into three sections, Tag Format, Tag Size and Tag Chip.
Also note that if you will be placing the NFC tag directly onto metal, then you must use either our 29mm on-metal NFC tag or our Industrial NFC Tag.
Seritag have two main tag formats - stickers and disc tags. Within stickers, there are white face and clear face. There's no scan distance performance difference between white and clear.
As a general rule, the larger the tag, the greater the scan distance or ScanStrength. ScanStrength is how close the phone needs to be to get a response from the tag. A larger ScanStrength or scan distance means the user experience is better as they don't have to 'hunt' for the tag or be so accurate with phone placement.
With mobile phones, the peak performance is around 36-40mm. After which, the phone doesn't have enough power and performance is flat and/or starts to reduce.
All our tags have been tested with all popular phones. We only stock the best tags and even our smallest tag will scan without problem. Phone performance varies but to give an idea, our smallest Midas tag has an average scan distance of around 2cm. Our 38mm size tag has an average scan distance of around 4cm. However, bear in mind that the vast majority of people do tend to almost or actually physically touch the tags (or the fabric/card/plastic in front of the tag) when scanning, then in reality all the distances are more than enough.
Seritag stock tags with four of the most reliable and powerful NFC chips on the market - the NTAG213, the NTAG210µ (NTAG210 Micro) and NTAG413/NTAG424. The 413/424 are specialist authentication chips which need advanced encoding and software so the majority of use cases will require either the NTAG213 or NTAG210µ.
To summarise, if :
There's a lot more information on the technical differences on our NTAG213 or NTAG210µ page.
