Having attended his first wedding on an Israeli kibbutz, Aaron Stone, a new immigrant from the U.S. pointed out: “I looked at a website here designed to help you calculate the amount you are supposed to give the couple. If you know the bride more than 5 years, NIS300, more than 10, NIS1000, if you slept with the mother, you need to get them a car and stay away. It is all so odd.”

Help is soon at hand, though, following the collaboration between researchers and a number of banks and fashion houses. Now, guests can either securely leave cheques in a safety deposit box stitched into the Rabbi’s hat, throw new magnetic shekel confetti at the happy couple, or swipe credit cards at one of the wedding chuppa’s four poles, each sponsored by Mastercard, Visa, Bank Hapoalim and Bank Leumi. 5G WiFi will connect each of the poles to the most favorable exchange rates, which are etched onto the Ketubah marriage contract with a laser pen. Fathers of the bride and groom will both be able to wear special voice-activated black pants that drop on hearing the words Mazel Tov, to reveal a compact cash register.

New brides will have the option of wearing an electronic white hoodie, which holds notes and coins, and is linked by Bluetooth to the groom’s bowtie, which sorts the currency into dollars, pounds and other major currencies. Gucci, Armani and Cofix will be bringing out wedding dresses with trains and veils made from perforated standing order and direct debit instructions if guests prefer to spread payments. A secret pilot scheme was launched at the wedding of noted selective tax-payer Bar Refaeli. When the wine glass was smashed, guests could be heard screaming “Mazel Tov” and “I’m broke” simultaneously. The products will be available from Sunday for purchase by the general public on one of the hidden floors at the Dizengoff shopping mall.
