Traditionally, we take a small piece of paper with a printed number on it from a queuing machine in the bank. Aiming at saving paper and slower the deforestation, we replace the traditional paper with the seal. The design combines a traditional seal with a queuing machine so that the customer can have a queuing number marked on the palm or some other places. The seal utilizes a special printing ink which can be easily erased once the transaction is done. It’s rapid and environmentally-friendly.
