Hi everyone, I just came back to BKK through Suvarnabhumi. Just informing they are already implementing the digital print machines and it seems to work fine, no hassles at all.
Also I've realized lately that is much easier and nicer to pass immigration in BKK than in DMK.
TLDR : Answer Summary
A recent traveler shared their positive experience passing through immigration at Suvarnabhumi Airport (BKK), highlighting the efficient implementation of digital print machines and noting that it was a smoother process compared to Don Mueang Airport (DMK).
