Yes happened to me, did the fingerprints she stamped my passport. Then putting all our hand luggage through the scanner then I got tapped on the shoulder, the officer said can you come with me. I said to my husband we need to go with him, he said no just you, said your fingerprints don't match. He took me back to the booth made a guy who was being processed stand back and everyone in the queue was looking at me. I was tested again and all ok. He was all smiles and me to but couldn't understand why she let me go through...Been back since no problem
