"Customer Identification purposes" mentioned in the 1st paragraph is strongly related to KYC/Know Your Customer process.
Mostly because if the system flagged that either the reciever or the sender (depends on whose system which detected it) subjects compliance department and need to give their identities, reason to send the money, relationship between the sender and receiver and sometimes even the proof of relationship and/or the proof of how the money obtained/used.
Unfortunately in South East Asia, Thailand, Indonesia and Malaysia are on top of the fraud suspected countries.
