parsing, by the one or more processors, the data indicative of the barcode using the corresponding public key;

in response to parsing the data indicative of the barcode using the corresponding public key, determining, by the one or more processors, authentication information from the data indicative of the barcode that indicates whether the first client device corresponds to an account;

in response to determining that the first client device corresponds to the account from the authentication information, determining, by the one or more processors, an account limit for the first client device from the account;

determining, by the one or more processors, a service requested amount found in the authentication information from the first client device does not exceed the account limit; and

in response to determining the service requested amount does not exceed the account limit, transmitting, by the one or more processors, data indicative of an acceptance of the requested service to the first client device.

8. The non-transitory, computer-readable medium of claim 7 , wherein the barcode comprises a one dimensional bar code or a two dimensional bar code.

10. The non-transitory, computer-readable medium of claim 9 , wherein the first client device is a wearable intelligent device and the second client device is a mobile device.

11. The non-transitory, computer-readable medium of claim 7 , wherein determining the authentication information from the data indicative of the barcode comprises:

determining, by the one or more processors, a unique ID of the first client device from the data indicative of the barcode; and

determining, by the one or more processors, account information of the first client device from the data indicative of the barcode.

12. The non-transitory, computer-readable medium of claim 11 , further comprising:

determining, by the one or more processors, a preconfigured account status for the first client device in the account that indicates whether the first client device is enabled for use; and

in response to determining the preconfigured account status for the first client device is enabled, determining, by the one or more processors, whether the unique ID and the account information of the first client device links to data found in the account.

13. A computer-implemented system, comprising:

one or more computers; and

one or more computer memory devices interoperably coupled with the one or more computers and having tangible, non-transitory, machine-readable media storing one or more instructions that, when executed by the one or more computers, perform one or more operations of one or more processors comprising:

sending, by one or more processors, a private key to a barcode device configured to encrypt data indicative of a barcode;

receiving, by the one or more processors, encrypted data indicative of the barcode from the barcode device in response to the barcode device scanning the barcode on a first client device requesting a service and based on the private key sent to the barcode device;

decrypting, by the one or more processors, the encrypted data indicative of the barcode using a corresponding public key obtained by the one or more processors to generate data indicative of the barcode;
