Tamper evident to increase Security! The security technology incorporated into the SecureSeal Deposit Bag obsoletes the traditional canvas lock and key bag. Each SecureSeal Deposit Bag has dual consecutive serial numbers for identification by the sender and receiver. The SecureSeal Closure, a maximum-security adhesive closure, provides state of the art tamper evidence, while the consecutive numbering creates complete tracking of successive deposits and a very convenient dispensing method. Security bags save time at the bank, allow others to make deposits easily and create a tight cash management environment discouraging theft.
