NFC Encoder High-Speed NFC Tag Encoding
There are several factors that determine the maximum encoding speed that can be achieved. It is best to start off slow and verify the tags are being encoded correctly and then gradually increase the speed until a stable point is reached. The NFC Encoder software can achieve encoding speeds greater than 5 tag/sec with the correct conditions!
- Tag Dimensions: Each NFC tag has it’s own physical size. The larger the size of the tag, the faster the linear web speed can be. This doesn’t effect the encoding speed (# encoded tags/sec), only the web speed.
- Inlay Type: The bigger the NFC inlay the faster it can be encoded, smaller inlays are slower to be encoded.
- NFC Chip Type: Each NFC chip is different and has it’s own reading and writing speeds. The NXP NTAG series is the fastest.
- Data Size: The “air speed” of NFC is fixed, therefore the more data that is written the longer it will take to write. As a general rule you should minimize the amount of data written to the NFC tag, as this also effects the reading duration.
- Locking: Making an NFC chip read-only will take a small additional amount of time.
- RF: The more stable and consistent the tag’s RF field is, the faster the encoding. When manual encoding, the human hand can not reliably create a stable RF field. NFC encoding hardware systems are designed to create a stable RF field for the tags and can therefore encode as faster speeds with higher quality.
Supported NFC Readers
Only a specific small set of NFC readers are able to be used for high-speed encoding. These NFC readers must be explicitly enabled in the NFC Encoder software settings; enabling the “Direct” NFC reader types. These NFC readers along with the Direct reader type support multiple NFC tags to be in the RF field at one time. This allows for high-speed NFC tag encoding when tags are close together, as is with the case when the tags are on a roll. This is also used along side automated hardware systems. There are a couple NFC readers that work with this type mode of encoding, each with its pros and cons.
The ACS ACR122U has a small antenna and should be used in situations where the NFC tags can be precisely placed over the NFC reader face. This requires a hardware system to control the placement of the tags. The ACR122U can handle NFC tags of all sizes, including the smaller inlays as long as the tags are precisely placed on the NFC reader face. The NFC tag shoudl be placed over the bottom of the inner rectangle and about 1″ off the reader face on the GoToTags branded models.
NXP Pegoda 710
The NXP Pegoda 710 has a large antenna and is intended to be used in situations where the precise positioning of the NFC tags compared to the NFC reader is not possible. This is often the case with non-roll based products such as wristbands or key chains. The Pegoda 710 can also be used in-line with existing systems that do not have NFC tags closely spaced. There is a limitation of the Pegoda 710 reader, it can not handle more than 4 NFC tags in its RF field at any one time. For example, this is the case when encoding the smaller inlays types (Midas, Circus…) when on a roll. The Pegoda 701 NFC reader only supports x86 based operating systems; it will not work on x64.
