"Tipit" is the world’s first card reader that makes it possible to transparently leave tips for staff with a bank card, phone or smartwatch. It's a cashless tipping device.The idea of the product was inspired by an existing problem of not being able to say "Thank you for your service" with tips when paying at the bar or restaurant with a card or smart device. The principle of usage was inspired by amplifier design where the potentiometer wheel is being rotated to adjust sound settings, while in this case it is rotated to adjust the amount of tips to be given. The process was full of challenges to discover a new user scenario for tipping. Final product is made in small series by a local production on demand. Soft touch of the product is very suitable for using the product and disinfecting it at the end of the day. The screen angle is bend to the proper position to be perfectly visible for users. The potentiometer attracts people to play and experiment with the device which encourages people to leave a tip for the stuff even more.
