[Cyberpunk: Edgerunners] What was Lucy pick pocketing? Are those chips some form of wallets or something else?

Not sure if those were wallets... or if she's just selling implants.

Datashards containing money.

Datashards can contain all sorts of information. videos, images, schematics, braindances etc...

They are also used as a tool for holding and transferring currency. Most people have multiple slots that they can slot datashards into. One of them being a datashard they use as a wallet. 

They likely don't contain the entirety of a persons savings and are more for day to day use.  As a netrunner, Lucy looks up her victims information and forcibly ejects the datashards without the victims knowing.
