function safeTransferFrom(address _from, address _to, uint256 _id, uint256 _value, bytes _data) external
Transfers
_value amount of an _id from the _from address to the _to address specified (with safety call). @dev Caller must be approved to manage the tokens being transferred out of the _from account (see "Approval" section of the standard). MUST revert if _to is the zero address. MUST revert if balance of holder for token _id is lower than the _value sent. MUST revert on any other error. MUST emit the TransferSingle event to reflect the balance change (see "Safe Transfer Rules" section of the standard). After the above conditions are met, this function MUST check if _to is a smart contract (e.g. code size > 0). If so, it MUST call onERC1155Received on _to and act appropriately (see "Safe Transfer Rules" section of the standard).

Transfers
_values amount(s) of _ids from the _from address to the _to address specified (with safety call). @dev Caller must be approved to manage the tokens being transferred out of the _from account (see "Approval" section of the standard). MUST revert if _to is the zero address. MUST revert if length of _ids is not the same as length of _values. MUST revert if any of the balance(s) of the holder(s) for token(s) in _ids is lower than the respective amount(s) in _values sent to the recipient. MUST revert on any other error.
MUST emit TransferSingle or TransferBatch event(s) such that all the balance changes are reflected (see "Safe Transfer Rules" section of the standard). Balance changes and events MUST follow the ordering of the arrays (_ids[0]/_values[0] before _ids[1]/_values[1], etc). After the above conditions for the transfer(s) in the batch are met, this function MUST check if _to is a smart contract (e.g. code size > 0). If so, it MUST call the relevant ERC1155TokenReceiver hook(s) on _to and act appropriately (see "Safe Transfer Rules" section of the standard).

function uri(uint256 _id) external view returns (string)
Get the URI for a voucher type
Name | Type | Description |

[0] | string | URI for token type |
function setBaseURI(string _value) external
Set the base url for all voucher types @param _value The new base url
function balanceOf(address _owner, uint256 _id) external view returns (uint256 bal_)
Get the balance of an account's tokens. @param _owner The address of the token holder @param id ID of the token @return bal The _owner's balance of the token type requested
function balanceOfBatch(address[] _owners, uint256[] _ids) external view returns (uint256[] bals)
Get the balance of multiple account/token pairs @param _owners The addresses of the token holders @param _ids ID of the tokens @return bals The _owner's balance of the token types requested (i.e. balance for each (owner, id) pair)
