What is a PK file?
A PK file is an electronic ticket or boarding pass you can add to your Apple Wallet. It can contain a pass provided by a vendor, like Delta Air Lines or Ticketmaster.
PK files typically contain additional information, such as confirmation codes and payment information. This makes them convenient for storing and using your passes on the go.
A PK file can also be a custom pass created by a user. This means you can personalize your passes to fit your needs.

Direct Banking
Direct banking can be a convenient option for those who prefer to manage their accounts in person.
In the past, withdrawals required a visit to the branch where the account was held, but today, customers are more commonly verified by PIN and through automated teller machines.
For people who feel uneasy with telephone or online banking, using a passbook is an alternative to obtain their account activity in real-time, without waiting for a bank statement.
Unlike some bank statements, some passbooks offer fewer details, replacing easy-to-understand descriptions with short codes.
