I run a clothing store and currently track loyalty points in Excel / Google Sheets. I now want to issue NFC NTAG213 cards so a customer can simply tap their card with any Android or iPhone and be taken to a mobile-friendly Google Sites page that shows four read-only fields pulled live from my sheet: Customer Name, Customer ID, Available Points, and Tier. Key points you will be working with • Cards store nothing except a single URL; all data must load server-side via the Customer ID embedded in that link. • No on-phone redemptions, edits, or app install—purely a display page. • Google Sites is the preferred front-end, backed by Google Sheets (or any equally lightweight intermediary) for the data lookup. • Design should stay simple and clean so it loads quickly and matches my minimalist in-store aesthetic. What I need from you 1. A working demo using sample customer records that I can test on both Android and iOS. 2. The final Google Sites template (or HTML if Sites limitations require a small embed) styled to match the store’s branding. 3. Step-by-step instructions on encoding and issuing additional NTAG213 cards, including best practices for batch programming. 4. Clear documentation so my team can add new customers, adjust point balances, and tweak tiers without touching code. I’ll supply the current sheet structure, loyalty rules, and Customer ID format as soon as we start. If you’ve built similar tap-to-view loyalty or membership solutions before, please point me to them—seeing a live example will help me feel confident we can get this done quickly.
