Perfect Forward Secrecy (PFS) enhances security in inter-branch banking transactions in several ways:

1. Ensuring that the compromise of one set of keys does not compromise past session keys: This means that even if a hacker manages to get hold of a current encryption key, they cannot use it to decrypt past transactions. This is because each session uses a unique key, so the compromise of one does not affect the others.

2. Encrypting each transaction with a unique key: This is a key feature of PFS. Instead of using a single key for all transactions, each transaction is encrypted with a unique key. This means that even if a key is compromised, only the transaction that used that key is at risk. Other transactions remain secure because they were encrypted with different keys.

3. Using a single master key for all transactions to simplify key management: This is not a feature of PFS. In fact, PFS avoids this approach because it creates a single point of failure. If the master key is compromised, all transactions could be decrypted. PFS enhances security by using unique keys for each transaction.

4. Mandating the use of hardware security modules for key storage: While this is not a specific feature of PFS, it is a good security practice. Hardware security modules provide secure, tamper-resistant storage for encryption keys. This makes it more difficult for hackers to steal the keys, further enhancing security.

In summary, PFS enhances security in inter-branch banking transactions by ensuring that the compromise of one key does not affect past or future transactions, and by using unique keys for each transaction.
