It depends on *which* law. They can require anything they want.
The Public Profile is the Thing though. What is Public? Certainly your SIN is, maybe any licenses or certifications. But what is in my Pocket, or in my body, is not mandated to be attached to the public profile of the PAN. As I said before, whatever you choose to broadcast is fine and dandy, but the vast majority of information that a public/corporate servant (read police/security) would need is only your SIN. Maybe some of your more important Biometrics. My medical file, what I own, what cyberware is implanted, is not part of your public profile at all. It might be something that you could release if needed, along with Licenses or certifications, but they should NOT be part of your public information that everyone reads. Unless you choose it to be.
By Default, Your SIN provides only the following Information, Per SR4A.
QUOTE
The actual numbers that compose a SIN are generated by a complex formula from several pieces of personal data. What this means is that law enforcement officials can determine your birthdate, state or country of origin, citizenship, and initials from your SIN.
And, why would they need anything else for a random sweep, as is the case in most zones where your Comlink must be in Active Mode.
Additionally. Same reference...

It used to be that one’s SIN and other forms of identification were all stored on credsticks, pen-sized tubes that served simultaneously as ID and credit card. Since the Matrix went wireless, however, all of this information was transferred to the commlink, and credsticks only survive as certified but relatively anonymous means of payment. In addition, all of a person’s credentials and necessary personal data (licenses, credit history, health insurance, cred accounts, etc.) are stored in encrypted form on her commlink (with a default Encryption rating of 5).For privacy reasons, this information is usually not broadcast as part of their personal profile for social networking, though some high-security areas may require that key information (particularly name and SIN) be broadcast. These personal details can also be transmitted (again in encrypted format) on an as-needed basis, as authorized by the user. For example, a store may ask for your cred account information (and possibly credit history or even licensing if you’re buying restricted goods), a hospital will ask for your medical records and insurance, while a security checkpoint might demand your SIN, passport, and criminal record. For security purposes, such data can also be transmitted at a lower Signal rating, via a short-range, line-of-sight infrared beam connection, or by physically linking the commlink to a terminal and transmitting by fiberoptic cable.
So, as can be seen. The majority of your data is NOT transmitted in Active Mode, as part of your public profile, unless there is reason to dig deeper.
That should cover it quite nicely, I believe.
