9 months ago It's not as simple as writing the SKU as text to the NFC tag. If you want to go that route, you'll have to copy the data from an existing RFID tag to the NFC business card, using an app like NFC Tools or a tool like the Flipper Zero.
tried to read the SKU from a business card. Wrote the text S0722520 on the card and tried to use the card to switch the roll. But the card is not recognized by the printer, what can I try to get it to work?
Got this tip from the forum: Switching between rolls can be done using either another original roll (which is then learned) or by using a simple of the shelf NDEF Tag where you just write the SKU of the roll (e.g. "S0722430") inside (like you do with business card information, any phone can do this nowadays). So by presenting either an original roll the complete data is learned, or by presenting a normal RFID NDEF tag with the SKU inside to choose from the pre installed tags is enough to switch between rolls. This makes it possible to modify the printer once and then no need to open again in order to switch roll types.
