This biometric symbol is usually printed on the front cover of biometric passports (), indicating that an electronic chip has been embedded in the passport and the polycarbonate leaf in the front of the passport
NFC materials store the amount of material left on the spool. During printing with NFC materials, the UltiMaker S5 and UltiMaker S7 utilize the flow sensor to track material usage and write the new amount to the NFC chip. The amount of material spool is displayed on the user interface via a battery icon.
Material usage tracking
NFC materials store the amount of material left on the spool. During printing with NFC materials, the UltiMaker S5 and UltiMaker S7 utilize the flow sensor to track material usage and write the new amount to the NFC chip. The amount of material spool is displayed on the user interface via a battery icon. The charge of the battery reflects the amount of material left on a spool. The battery icon is also visible in UltiMaker Digital Factory.
The battery shows 4 full bars when the spool is new and the battery empties as the spool of filament depletes. For materials that lack an NFC chip, the battery contains a ‘?’ icon.
Note: Although material usage is tracked on the NFC chip, this information will never be used to determine end-of-filament. This data may be incorrect. For example, if the spool was also used on a printer without NFC functionality. The Pro Bundle contains various sensors to trigger end-of-filament without relying on NFC data.
When an end-of-filament situation occurs, the Pro Bundle will automatically select the next material of the same type and resume printing.
Note: When there are two materials of the same type loaded into the Material Station, the Pro Bundle will always consider the first loaded material spool as the oldest spool and therefore the first in line for printing.
One-touch simplifies your life
The new NFC technology offers you the One-touch function, which will allow you to play your music in a matter of seconds. With a simple touch of your Smartphone to the SRS-BTS50 speaker you can connect, disconnect, and switch connections between NFC-enabled devices. Going from your playlist to that of your friends will be very simple with One-touch
Bambu Lab also uses RFID with their 3D printers and filament, specifically for the AMS, their automatic material system. Since it allows you to use 4 materials (or 16 if you connect 4 units at the same time), the tags store the type of filament and the color, to make configuration much faster. Automatically loads the info when they’re slotted in. Thankfully, there’s no usage info, so they don’t “go bad”. The rolls split apart to refill, and you can either buy refills on their site (rolls with no spool), or you can harvest the filament from another brand. They also aren’t mandatory, you can still manually configure every slot in the AMS.
Apparently the tags are mifare classic 1k based, with detection of gen1 magic tags, so using your own is tricky. Found some photos online:
