# Touch 'n Drink

Touch 'n Drink is a small device that reads NFC id cards of club members of the [Aeroclub (LSC) Hamm][LSC Hamm] and allows to pay for items like cold drinks offered at the clubhouse. Purchases are forwarded to accounting so members pay via their regular monthly invoices. We're located at airfield [EDLH] in Hamm, Germany.
