We’re attempting to build a combined thermal printer and RFID reader using Spark Core. The device will read a user’s RFID card, send the card’s ID to a server which looks up that user, send some relevant information back to the Core, which prints it on the printer.
Is this likely to be possible? Looks as though we can use both Serial and Serial2, so both devices can be connected okay. But what about reading an ID from the RFID card and sending it to the server? And sending bitmaps to the printer?
Thanks for your thoughts.
