The main challenge for flexible metal-oxide RFID tags is to fully comply with the ISO14443-A NFC standard to enable readout by standard NFC reader or handheld devices, due to the limited charge carrier mobility of the semiconductor and multiple sources of parameter variation caused by roughness, temperature and dimensional stability of the foils. Recent work by various groups [1-4] demonstrated only an incremental improvement in data rates from 50b/s to 396.5kb/s to be compatible with ISO14443 (105.9kb/s). In this work, we present
