The new electronic payment and loyalty system in ICW self-service car washes is the IMpuls key. The key is made in the form of a keychain, it can be hung on the keys and always carried with you.
In our opinion, it is much more convenient than the card that we have in our wallet just to put anywhere. On the Key we record the balance after receiving the money from the client for refilling the key. The client inserts the key into the chip slot, the balance of its key is displayed on the display and it can perform washing operations.
