The personal electronic device is configured to communicate identity information and/or account information to the peripheral device that, in turn, can be used to enable gameplay on the electronic gaming machine. Other embodiments described herein reference a network architecture facilitating cryptographically-secure and verifiable accounting of all point or real-money transactions in a casino environment. ## Claims ### Claim 1 A system for transacting with player accounts in a casino environment, the system comprising: at least one electronic gaming machine including a gaming machine processor and mobile interface device; a peripheral controller facilitating communications between the at least one electronic gaming machine and one or more peripherals associated with the electronic gaming machine; at least one internal server; at least one external server; and a dedicated processing unit, separate from the gaming machine processor, configured to: secure a communication channel between the mobile interface device and a personal electronic device; receive and verify identifying information from the personal electronic device; receive an account balance from the personal electronic device; and send an instruction to the peripheral controller associated with the electronic gaming machine to credit the electronic gaming machine with the account balance. ### Claim 2 (depends on 1) The system of claim 1, wherein the account balance relates to a bank account. ### Claim 3 (depends on 1) The system of claim 1, wherein the account balance relates to a player gaming account. ### Claim 4 (depends on 1) The system of claim 1, wherein the identifying information is verified via the at least one internal server or at least one external server. ### Claim 5 (depends on 1) The system of claim 1, wherein the account balance is received with a cryptographic signature that verifies the account balance is genuine and up-to-date. ### Claim 6 (depends on 1) The system of claim 1, wherein the peripheral controller facilitates communications between the at least one electronic gaming machine and a bill validator and printer associated with the electronic gaming machine. ### Claim 7 (depends on 1) The system of claim 1, wherein the dedicated processing unit is further configured to unlink communications between the mobile interface device and the personal electronic device based on a location of the mobile interface device. ### Claim 8 (depends on 1) The system of claim 1, wherein the peripheral controller is in communication with one or more of the at least one internal server and the at least one external server. ### Claim 9 A method of funding an electronic gaming machine having a mobile interface device comprising: securing a communication channel between the mobile interface device of the electronic gaming machine and a personal electronic device; facilitating communications between the at least one electronic gaming machine and one or more peripherals associated with the electronic gaming machine; utilizing a dedicated processing unit, separate from the gaming machine processor, for: receiving and verifying identifying information from the personal electronic device; receiving financial account information from the personal electronic device; and sending an instruction to a peripheral controller associated with the electronic gaming machine to credit the electronic gaming machine with funds from a financial account related to the financial account information. ### Claim 10 (depends on 9) The method of claim 9, wherein the financial account is a bank account. ### Claim 11 (depends on 9) The method system of claim 9, wherein the financial account is a player gaming account. ### Claim 12 (depends on 9) The method of claim 9, wherein the financial account information is received with a cryptographic signature that verifies the account balance is genuine and up-to-date. ### Claim 13 (depends on 9) The method of claim 9, wherein the peripheral controller facilitates communications between the at least one electronic gaming machine and a bill validator and printer associated with the electronic gaming machine. ### Claim 14 (depends on 9) The method of claim 9, wherein the peripheral controller is in communication with one or more of the at least one internal server and the at least one external server.
