It was reported that Migración’s “Biomig” platform in El Dorados collapsed due to a bad phone line and passengers were told to be present four hours before hoped for departure. I haven’t traveled for a long time so new to me but evidently “Biomig” checks your face biometric ly against bad guys reported to Interpol et al. A friend who travels told me the biometric scan lets him whisk through with his electronic visa. Will be a while before l try it myself.
