Claims
- 1. A method of providing benefits comprising,
- indelibly writing, on a first area of a card, data denoting a first set of entitlements, with said first area of said card being an optical storage medium,
- reading said first area of said card and acquiring information representing a second set of entitlements from a possessor of said card,
- if said second set of entitlements is a subset of said first set of entitlements, then writing, on a second area of said card, data authorizing use of said second set of entitlements, said second area of said card being a magnetic recording medium, and
- reading said second area of said card and providing benefits according to said use of said second set of entitlements.
- 2. The method of claim 1 further comprising,
- indelibly writing, on said first area of said card, data denoting personal identification,
- reading said first area of said card and acquiring access information from said possessor of said card, and
- if said access information does not correspond to said data denoting personal identification, preventing said writing, on said second area of said card, of said data authorizing use of said second set of entitlements.
- 3. The method of claim 1 further comprising,
- erasing preexisting authorization data from said second area of said card, prior to acquiring information representing a second set of entitlements from a possessor of said card.
- 4. The method of claim 1 wherein said first area of said card has a semiconductor integrated circuit memory and said second area of said card has a magnetic storage medium.
- 5. The method of claim 1 wherein said first area is on a first side of said card and said second area is on a second side of said card.
- 6. The method of claim 1 wherein said first area is disposed on a first side of said card and has an optical recording stripe and said second area is disposed on a second side of said card and has a plurality of magnetic recording stripes.
- 7. The method of claim 1 wherein said first area has an optical recording stripe on a first side of said card, and said second area has a magnetic recording stripe on both said first side and a second side of said card.
- 8. The method of claim 1 wherein said indelibly writing and said reading are performed at different locations.
- 9. The method of claim 1 wherein said writing data and said providing benefits are performed at different locations.
- 10. The method of claim 1 wherein said reading said first area of said card, said acquiring a second set of entitlements from a possessor of said card, and said writing data are performed at a single location.
- 11. The method of claim 1 wherein said providing benefits is performed at a greater number of locations than said writing data authorizing use of said second set of entitlements.
- 12. The method of claim 1 wherein said writing data authorizing use of said second set of entitlements is performed at a greater number of locations than said indelibly writing data denoting a first set of entitlements.
- 13. The method of claim 1 wherein said first area of said card has an optical storage medium and said second area of said card has a semiconductor integrated circuit memory.
- 14. A method of acquiring benefits comprising,
- receiving a card having data denoting a first set of entitlements permanently encoded onto an optical recording medium,
- providing said card to a data conversion terminal and selecting a second set of entitlements,
- receiving said card from said data conversion terminal with data encoded on a magnetic recording medium of said card authorizing use of said second set of entitlements if said second set is a subset of said first set,
- providing said card to a benefits dispenser and receiving benefits according to said second set of entitlements.
- 15. The method of claim 14 further comprising providing personal identification and entitlements information to a writing terminal, prior to receiving said card having data denoting said first set of entitlements permanently encoded.
- 16. The method of claim 15 further comprising providing to said data conversion terminal a personal access code corresponding to said personal identification information, prior to receiving said card from said data conversion terminal with data encoded on said card authorizing use of said second set of entitlements.
