SCM3712 REFERENCE MANUAL 26
5.3. Antenna
The SCM3712 and the SCM3712NFC reader come with an integrated antenna, while the SCM3712
ANT comes with an external antenna. Any of those ready to use antennas do not require any tuning
as the antennas already are being tuned for optimized performance during the production process.
Any changes on the tuning circuit will result in a negatively influenced reader performance.
