To address this problem, GeeDee86 let me have some redundant cards to play with, and I managed to turn the cards into bracelets.
Caveat: This technique should work on most cards with RFIDs embedded, but be aware that it is not acceptable to do it to some payment cards, such as the Oyster card you use to pay for your London commute. Check the ToS of your particular card, and look for clauses on mutilation.
Step 1: Materials and tools
- Non-polar solvent, such as nail varnish remover, paint thinners, acetone or petrol.
- Shallow non-plastic tray or dish.
- Tools to prod and stir. Wooden coffee stirrers, metal forceps or narrow-nosed pliers are ideal.
- Non-metallic material to make a bracelet. I used a popsicle stick, but you could use papier mache, thin plywood, heavy fabric, scrap acrylic etc.
- Tools appropriate to your materials
- Glues or paints as required to finish the bracelet materials, if desired.
Safety: Most non-polar solvents can cause contact dermatitis, so I recommend using protective gloves and eye protection. You also need to ensure that you have plenty of ventilation, as the fumes are toxic and do odd things to your head, and the fumes of most solvents are highly flammable, so be aware of your personal fire precautions.
*I have no images of the cards before starting the project, in order to comply with Data Protection legislation.
