I've been to multiple countries where they read the RFID in the passport for automated border control, and if you don't have an RFID-capable passport they revert to manual inspection where you may be asked uncomfortable questions.
I'd rather use an RFID-safe pouch to store my passport and use the RFID-based automatic border control.
The kind of uncomfortable questions asked by racist border agents who assume anyone with a darker skin color will have obtained a visa fraudulently, or will overstay their legitimate visa.
My fun, pre-RFID traveling days... always ended up with me in secondary screening. Millions of non-citizens, waived right-on-through... and then these two Texian gringoes... getting their beat-up, licensed & insured Z71 thermally scanned at every possible Rio Grande crossing.
