7. Can companies providing mobile phone services record my ID card number or collect a copy of my ID card if I apply for their services?

These companies operate on the basis of deferred payment (i.e. customers are usually required to make monthly payment after using their services). Hence, they require a means of proving the identity of their customers in order to obtain payment. Moreover, they face the problem that the services concerned are not provided to a fixed location. On the other hand, there have been a number of reported cases of individuals fraudulently obtaining such services using another person's name and address, and of the salespersons opening accounts for fictitious persons to defraud their company. For these reasons, the collection of the ID card numbers and copies of the ID cards is generally justified under the Code. However, these companies should mark the word "copy" across the image of the copies.
