Let me start with the first line after the heading. "The Contactless Cards Management System V6.9 boasts an array of innovative features that make it an ideal solution for card management."
Wait, the user also said "only output text," so I shouldn't add any headings or extra text. Just the converted text. Let me check if I missed any proper nouns. "Contactless Cards Management System V6.9" is a proper noun; no synonyms there.
Okay, the user wants me to generate synonyms for all words in the provided text, but keep the proper nouns untouched. First, I need to identify which parts are proper nouns. "Contactless Cards Management System V6.9" is definitely a proper noun and should remain unchanged. "Download Link" is probably a label, so maybe it should stay as is, but the user said to change all words except proper nouns. Wait, the user might consider "Download Link:" as part of the text, so maybe "Download Link" is not a proper noun. Hmm, but "Download Link:" in the second paragraph might be a heading. Let me check the original instruction again: "convert every word with 3 synonyms using syn1 format. Proper nouns stay." So, the key is to identify if any words in the text are proper nouns. The first sentence mentions "Contactless Cards Management System V6.9" which is the name of the software, so that's a proper noun. Everything else like "Contactless" and "Cards" are part of the name. The rest of the words are regular words that need synonyms.
I need to be careful with technical terms. For example, "registration form" could be "enrollment form|user setup sheet|account creation document".
